The chinese sentences above are "Unable to establish connection to server".
I have check my firewall, cargo isn't blocked, and there is personal CA installed by Adguard, no proxy.

Notes
OS: Windows 7 64bit, mingw64 with MSYS2
Output of cargo version: cargo 1.29.0

alexcrichton · 2019-01-02T17:57:55Z

Hm is this perhaps a network-level issue where github.com or github.com/rust-lang is blocked? Otherwise I'm not sure how we'd fix this as it seems Cargo can't connect :(

weiby3 · 2019-01-02T19:03:51Z

I try git clone and curl https://github.com/rust-lang and they works fine.
On my computer github.com can be accessed successfully, I have search the firewall and there aren't any block rule related to it.
Maybe these are some useful information.
I use HUORONG SECURITY as my anti-virus software, and if there is a program trying to connect to Internet, it will popup a windows and ask for permission.
Strangely when I run cargo run --verbose there is no popup window, but if I run curl https://github.com/rust-lang there is a popup window, so it seems Cargo can't connect.
Is it possible to get more error information?

alexcrichton · 2019-01-02T19:29:07Z

Hm so AFAIK there's a few different ways to touch the network on Windows, and it may be that Cargo, through libgit2, is using a different way that's may blocked or doesn't provide a popup? Can you temporarily disable your firewall/virus scanning to see if that fixes the issue?

ddw360 · 2019-01-03T00:50:06Z

@alexcrichton Disabling antivirus, firewalls, etc - don't seem to work. I was able to do a cargo build in Windows 10 x64 but not in Windows Subsystem for Linux. Both have versions re: nightly, etc. The build fails when trying to retrieve from github dependencies. Command issued was "cargo build --release --target=wasm32-unknown-unknown"

alexcrichton · 2019-01-03T16:17:27Z

Hm interesting! So this probably isn't a firewall/antivirus issue if you've disabled all those and it still didn't work. It works on Windows though and not the WSL? What we use on Linux is far more bog-standard I think than the Windows implementation, so I'm surprised it wouldn't work there if it works on Windows... I wonder if that's a WSL bug?

ddw360 · 2019-01-03T17:46:18Z

WSL environment info:

Don't know if it matters or not - but here are contents of Cargo.toml below and the git repos that the cargo build command is trying to pull for dependencies. when "cargo build --release --target=wasm32-unknown-unknown" is issued. Fails on trying to resolve the first "hdk" dependency.

Can you perhaps try strace? That may help illuminate which syscall is failing and may help tracking this down?

weiby3 · 2019-01-04T01:31:09Z

Sorry for late response.
I have tried to disable firewall and anti-virus software, but it still has this problem.
Is it possible to expose the download directory filename and/or commands? Maybe try to do it by myself can solve this problem.

ddw360 · 2019-01-04T01:34:51Z

@weiby3 @alexcrichton Weiby3 - I am curious if you are in actual Windows standard command line, powershell or a WSL environment when encountering issues. I haven't tested doing things in Powershell but do get the spurious network error in WSL.

weiby3 · 2019-01-04T08:18:08Z

I have tried in cmd.exe and got the same problem. Windows 7 doesn't have WSL, so I can't try. Powershell also not work.

alexcrichton · 2019-01-04T16:34:03Z

@ddw360 do you perhaps have a proxy configured? It looks like an ntlm proxy or something like that, running on port 3128

ddw360 · 2019-01-04T19:29:46Z

@alexcrichton don't think so - here is my evidence:

from Windows cmd prompt: netstat -abno | findstr /R "^.:3128.$" --> no results
Internet Explorer Settings - no proxy being used for internet connection
whatismyipaddress:
Hostname: | cpe-76-170-98-202.socal.res.rr.com
Services: None detected
Proxy server not detected.
Broadband
Dynamic IP
netstat from bash (ubuntu 16.04) shows no use of proxy port 3128
/etc/resolv.conf shows no use of proxy - nameservers are all gateway addresses and then gateway pointed to publ
ic dns/internet
git version is 2.7.4 (<< i am going to try to get a later version of git by compiling from source and see if that does the trick since cargo relies on git - since current ubuntu is 16.04).

I am going to try to move to WSL ubuntu 18.04 LTS and a higher git version and see if that changes things at all.

weiby3 · 2019-01-04T20:26:00Z

If I try to run cargo via a proxy, it can "Updating registry https://github.com/rust-lang/crates.io-index", but it will get the following output:

@alexcrichton upgrading to WSL ubuntu 18.04, git 2.20.1, lastet rust and cargo nightly has not resolved.
Could this be related to: #1180 in any way?

alexcrichton · 2019-01-07T15:36:18Z

This doesn't look related to certificate validation just yet, but your examples are also somewhat hard to follow for me :(. What caused the packages to actually be downloaded? It looks like in some cases connections to crates.io are disallowed but github is allowed. (I'm not really sure what's going on here...)

weiby3 · 2019-01-07T17:36:06Z

The project comes from a tutorial.
The following is Cargo.toml.

[package]
name = "guessing_game"
version = "0.1.0"
authors = ["account"]

[dependencies]
rand = "0.3.14"

ddw360 · 2019-01-07T17:52:30Z

@alexcrichton I am trying to run the holochain stack and an example project
See:
https://developer.holochain.org/start.html
https://github.com/holochain/holochat-rust

The "hc package" and "hc test" commands issue the following "cargo":
"cargo build --release --target=wasm32=unknown-unknown"

and it fails - with SSL related issues - per the pastebin's I posted.

For me - what I have is problems specifically in Windows Subsystem for Linux. And pathing to cargo or hc are not the problem - they both come up correctly in bash.

In Windows 10 cmd.exe and powershell - no problems once I made sure that cargo and rustc were properly in the system path.

@weiby3 is likely having different root cause? But same resulting error - re: SSL and Spurious and git?

@alexcrichton I am trying different projects in Windows Ubuntu 18.04 WSL - i.e. actix/examples. So cloned down the repo, go to the "hello-world" example and do cargo run. Get spurious network error. Firewall is turned off, no antivirus running, etc.

@d3sbar I stuck in same error. Fix that by removing [http_proxy] field in ~/.cargo/config.

WindSoilder · 2019-08-14T09:13:30Z

Got the same issue while Updating crate.io index... The error message is:

warning: spurious network error (2 tries remaining): HTTP parser error: stream ended at an unexpected time; class=Net (12)

But I think it's just caused by my Network problem...

I use wireshark to capture segments between my host and github(The ip address is 13.229.188.59).

From wireshark, I find the following phenomena:

github have tried to send many Retransmission for the same segment and,
my host is sending and sending back duplicate ACK.

~~It seems that my ACK can't reach github machine in time~~
It seems that it's just cause by network problem(like network congestion)

IMO, if there are stable Crates.io MIRROR exists in my region(Asia), the problem can be solved(by editing ~/.cargo/config).

Hope this information can help..

My OS: Mac 10.14.6
Cargo version: 1.36.0

baburkin · 2019-08-30T15:31:46Z

I got the same issue on Windows 7 and it looks like the reason behind that is cargo cannot find its way through our corporate NTLM proxy.

I was troubleshooting this with plain curl. When I try to run

curl https://github.com/rust-lang/crates.io-index

I get the response

curl: (56) Received HTTP code 407 from proxy after CONNECT

which implies that I need to authenticate in the proxy. By using curl with -vv option I can see that it tries to authenticate using NTLM:

...
Proxy-Authenticate: Negotiate
Proxy-Authenticate: NTLM

* Ignore NNNN bytes of response-body
* Received HTTP code 407 from proxy after CONNECT
* Closing connection 0
curl: (56) Received HTTP code 407 from proxy after CONNECT

Then what I did I added the following environment variables via Control Panel (the addresses are distorted on purpose):

HTTP_PROXY=http://ntlm-proxy.org.com:8080
HTTPS_PROXY=http://ntlm-proxy.org.com:8080
PROXY_USER=NT_DOMAIN\username
PROXY_PASS=the_password  <-- I know, not ideal, but see below

After that I was able to receive the crates index using the following command:

curl -vv --proxy-any -U : https://github.com/rust-lang/crates.io-index

It worked, it also worked with --proxy-ntlm instead of --proxy-any, but if I don't specify this parameter, I get the 407 error again. Instead of adding environment vars for user and password, I also was able to specify --proxy-user NT_DOMAIN\username and provide the password interactively - and it also worked.

So it looks like at the moment rust's cargo lacks support for NTLM proxy specifics, including authentication. Given that curl does support this, I think it is just a matter of adding this support in future versions.

Ideally, it would be nice to be able to to specify in ~/.cargo/config:

[http]
proxy = "host:port" # HTTP proxy to use for HTTP requests (defaults to none)
proxy-auth = "ntlm" # negotiate, basic, digest, etc... 
proxy-user = "username"
proxy-password = "password"
...

alexcrichton · 2019-09-03T14:47:31Z

Thanks for the investigation @baburkin!

This is unfortunately a pretty long a sprawling issue, mind opening a focused issue purely on supporting proxy authentication (aka NTLM)?

Thesoul20 · 2022-08-14T13:26:21Z

now i fixed it. in china, we need to set a china source for the crates: cd $HOME/.cargo nano config cat config

it shows:

[net] retry = 2 # network retries git-fetch-with-cli = true

[source.crates-io] registry = "https://github.com/rust-lang/crates.io-index" replace-with = 'ustc'

[source.ustc] registry = "git://mirrors.ustc.edu.cn/crates.io-index"

cd /path/to/some-rust-project/ cargo build --release

then u are set.

This worked for me.
But in the $HOME/.cargo directory, i have create a file named config.toml and write those command in the file.
OS: ubuntu 20.04 China.

not sure exactly what finally did it for me, but i plugged my laptop into ethernet and it worked fine first time after that. i wonder if its packet loss on the streams over my wifi. try it somewhere reliable and fast...

rikonaka · 2023-01-13T05:16:25Z

My situation is because my git proxy is configured, and I temporarily turned off the git proxy to fix it.
git config --global --unset http.proxy  
git config --global --unset https.proxy

It's save my life. 😘

asears · 2023-02-10T12:37:26Z

It's amazing this is still open in 2023! My fix was to allow the crate.exe through Windows Defender Firewall.

In my case I am setting up a new rust-up cargo install on a Windows 10 machine with latest git cli installed. I used the 64-bit Windows installer from the downloads page because the chocolatey installer appeared out of date with 1.25.1 instead of 1.25.2 and flagged with some scan warnings.

https://community.chocolatey.org/packages/rustup.install

Was testing the setup using the examples crate.

cargo install mdbook --vv

The --vv command didn't show any additional details.

Windows Firewall was not blocking the git client and was able to run both the inbuilt cargo git and use git cli git fetch options.

This worked fine both inside and outside of cargo, turning on and off the git fetch with cli option. Note the newer gh cli might be a good option to add to the list.

git fetch --force --update-head-ok https://github.com/rust-lang/crates.io-index +HEAD:refs/remotes/origin/HEAD -v

It was not the git step which was failing, it was the accessing of crates.io URL via a dynamic 6xxxx port.

Tested with curl and got following error

curl -vvv https://crates.io/api/v1/crates/mdbook/0.4.26/download

curl: (7) Failed to connect to crates.io port 443: Bad access

Allow an app through Windows Firewall might work, though I went the port route.
https://support.microsoft.com/en-us/windows/risks-of-allowing-apps-through-windows-defender-firewall-654559af-3f54-3dcf-349f-71ccd90bcc5c

I am using Malwarebytes Windows Firewall which added this pretty broad rule:
%USERPROFILE%.rustup\toolchains\stable-x86_64-pc-windows-msvc\bin\crate.exe
Allow
Out
Local ports: Any
Remote addresses: Any
Remote Ports: Any
Protocol: Any

Adding add rule to Windows Defender Firewall to the Windows installer or finding alternative approach might solve this particular issue.

The only workaround that worked for me on my Dockerfile was

ENV CARGO_NET_GIT_FETCH_WITH_CLI=true

I tried all other workarounds but they did not work

Hi, I had a similar issue recently. cargo build failed with this spurious network error message. I figured out that it was trying to clone a git repository as git://.... I tried git clone git://... manually and it really failed, however, git clone https://... worked. I added
[url "ssh://"]
    insteadOf = git://
to ~/.gitconfig as described here and then finally cargo worked, too.

Thannks. It works.

#  config file: ~/.cargo/config.toml
[net]
git-fetch-with-cli = true 
Test if it works.

OS: Windows 10
cargo: 1.53.0 (4369396 2021-04-27) rustc: 1.53.0 (53cb7b09b 2021-06-17) git: 2.31.1.windows.1
This was the fix for me! Thank you very much. I experienced the problems when building with Docker (Alpine Base). It was a cross ARCH build. Interestingly when I was build native there was not an issue. If anyone points that into a direction that helps.

That solution helped me get through the initial download issue (listed by OP). But now it fails with "Peer certificate cannot be authenticated with given CA certificates (SSL certificate problem: certificate has expired)" on https://crates.io/api/v1/adler/1.0.2/download

MacOS 10.14.5
Cargo 1.70.0-nightly
Firewall is off.

I have 0 issues with this on Windows or Linux, but for some reason MacOS can't build.

UPDATE: Calling cargo run multiple times resolves the new ssl issue. #11670 Still strange, and would be nice if that wasn't required.

This happens to me as well with a clean WSL Debian installation. First got it together with a Read-only file system; error upon rust installation. This worked again after shutting down WSL and try again. Now I get the same for cargo install upon downloading the crates.io index.

The command seems to corrupt WSL's filesystem completely, even got -bash: rm: command not found after running cargo install :-o

i also meet this problem , and the version is 1.70.0

rustup 1.26.0 (5af9b9484 2023-04-05) info: This is the version for the rustup toolchain manager, not the rustc compiler. info: The currently active rustcversion isrustc 1.70.0 (90c541806 2023-05-31)`

then i fixed it by update version to 1.68.0
rustup install 1.68.0 && rustup default 1.68.0

ooooooops · 2023-06-28T14:32:59Z

@weiby3 你好。我也遇到这个问题，你解决该问题没有？我至今未能解决。能否给点提示？非常感谢你的回复

@briteming 后面没事了，我也不知道怎么解决的

我是把网断了重连就好了

I use a similar solution with an additional "[email protected]" (for accessing private repo on github). It seems like the daemon service of git protocol doesn't work well with my proxy.

$ cat ~/.cargo/config.toml
[net]
git-fetch-with-cli = true

$ cat ~/.gitconfig

	insteadOf = git://github.com

ratankaliani · 2023-12-14T23:34:00Z

Ran into the same issue as @Hongqin-Li, my .gitconfig was incorrect, replacing it fixed this issue!

Demoevery · 2024-01-17T22:42:48Z

Using gitoxide solved it for me
cargo +nightly -Zgitoxide run

pengchenglv · 2024-04-14T08:18:27Z

edit .cargo/config.toml as follows to disable proxy. It works for me

[http]
proxy = ""
