Remote access results in 404 Not Found error (nginx/1.16.1) #1231

amirulmenjeni · 2020-03-04T13:45:48Z

I've set up and installed cvat on a remote PC connected to a LAN, from which I use my laptop to access cvat remotely. It seems like it's able to connect to cvat remotely, but there's no web page found, giving the 404 Not Found error as per the title.

I've set up the docker-compose.override.yml file as follows:

version: "2.3"

services:
  cvat:
    environment:
      ALLOWED_HOSTS: "*"
      UI_SCHEME: http
      UI_HOST: 192.168.10.4
    ports:
      - "80:8080"

  cvat_ui:
    build:
      args:
        REACT_APP_API_HOST: 192.168.10.4
        REACT_APP_API_PORT: 8080

The file docker-compose.yml is left as is.

After rebuilding with

docker-compose build

and starting the cvat server with

docker-compose -f docker-compose.yml -f docker-compose.override.yml up -d

the error still persists.

The text was updated successfully, but these errors were encountered:

it seems that you just need to specify CVAT_HOST as the installation guide shows. The method you use is deprecated

I'm using last develop commit (8afb5dda2a6471ff9274a6ac18c6a425786ddfea) on windows and face following issue:

cvat gui can't connect cvat database when I'm accessing cvat from outside of our vpn. I have forwarded a port (on homeip.net) and added CVAT_HOST: .homeip.net to docker-compose.yml

Gui is accessible (on <some_name>.homeip.net:38811) but when I connect I see following error message

Could not check authorization on the server
Open the Browser Console to get details

Opening the console, I see this message

xhr.js:160 GET http://<some_name>.homeip.net:33881/api/v1/users/self 502 (Bad Gateway)

I have added also ALLOWED_HOST: '*' to all container's environment section

so my docker-compose is now following:

In cvat's console, I see following messages

Another remark is, if I connect the gui while I'm connected to VPN (where the cvat is physically located) and set CVAT_HOST: 192.168.100.176, everything works fine

I have resolved this by replacing .homeip.net to exact ip of <some_name>.homeip.net

@amirulmenjeni Hi, is the issue still relevant?

yyc9268 · 2020-03-25T01:52:32Z

@RomanVeretenov
This helped. I added ALLOWED_HOST: '*' to environment sections and rebuilt the docker container. Then the login succeeded.

ArefAz · 2020-05-06T12:14:40Z

I have the same problem; 404 Not Found, nginx 1.18. What should I do?

I tried different workarounds but none of them worked.

My docker-compose.override.yml:

azhavoro · 2020-05-06T12:24:48Z

@ArefAz Hi, what version of CVAT do you use? (git log -1)
Please note since release 0.6.0 host and ports configuration is changed and you need setup only one env variable (CVAT_HOST) for the cvat_proxy container as described here https://github.com/opencv/cvat/blob/master/cvat/apps/documentation/installation.md#advanced-settings. Please follow this guide.

ArefAz · 2020-05-06T12:38:36Z

@azhavoro I'm using the latest version.

Thanks, I'll try that and will let you know.

tomalbrecht · 2020-05-26T06:21:58Z

@azhavoro Thanks this helped me. I had to use a wildcard though, because cav-ui seems to mix IPs on Client-Side (server and client ips). When I set CVAT_HOST only to the Client IP I will get 404 Errors - I think because the client won't be able to reach the server IP then (not verified). Nevertheless it does work with wildcard. Using only "*" as wildcard does not work either.

version: "2.3"

services:
  cvat_proxy:
    environment:
      CVAT_HOST: "192.168.178.*"

For version 3.3
only deleting server{...} block from cvat_proxy/conf.d/cvat.conf.template file and restarting solved the issue.

For version 3.3 only deleting server{...} block from cvat_proxy/conf.d/cvat.conf.template file and restarting solved the issue.

I've just clone cvat from github, and I can't find the cvat_proxy folder, can you please show me where is it?
I'm facing 404 error from outside too.

I've tried to search cvat.conf.template file in folder but not found

dps-s2@DPS-S2:~/cvat$ find *conf*
lint-staged.config.js
mod_wsgi.conf
supervisord.conf

Updated: I fixed the problem my self by update all CVAT_HOST value from localhost to my domain.

Thanks for your link, I've checked but dont understand why it must be the domain instead of localhost (sorry I'm not so good with technology)
