Afte view this issue (#10632), I have checked the port binding in wsl:

Can wsl use the port same with windows?

execute python -m http.server --bind 0.0.0.0 with windows, success
execute python3 -m http.server --bind 0.0.0.0 with wsl, failed.

Can windows access web started by wsl?

When I use edge in windows, I can access the web by 192.168.0.102, but 127.0.0.1 is not worked.

Similar issue.
If I kill all WSL processes and restart it, I can access Windows localhost:port again.
But if I leave it running for hours, I cannot access Windows localhost:port from WSL.

If you want to connect to the host from the WSL container by the IP address assigned you'll need to connect to 127.0.01. If you want to connect to the assigned address, you need to set [experimental] hostAddressLoopback=true (see https://learn.microsoft.com/en-us/windows/wsl/wsl-config#experimental-configuration-settings).

But in the original repro, it was sent to 127.0.0.1, so that's valid.
We see a RST immediately returned.

15:44:12.145100 IP 127.0.0.1.60816 > 127.0.0.1.7890: Flags [S], seq 2455237139, win 65495, options [mss 65495,sackOK,TS val 260823200 ecr 0,nop,wscale 7], length 0
15:44:12.145107 IP 127.0.0.1.7890 > 127.0.0.1.60816: Flags [R.], seq 0, ack 2455237140, win 0, length 0

Everything else looks setup correctly (Hyper-V Firewall is setup correctly).
This suggests one of 2 things that I can see:

the app wasn't bound & listening to that port at the time
Cisco's VMWare solution has filters that are causing issues
(I only bring up VMWare as we have observed many interop issues in the past).

I have uninstalled the VMWare just now and reboot the computer, but it still not work.

I think the app was bound the port at the time, because I can not access google without this proxy (google was blocked in my country).

And now I can access google(port is work in host), but telnet 127.0.0.1 7890 still can not work with wsl.

I tried disabling every service until I reached network-manager.service, and finally, the mirrored functionality started working properly. It took me a significant amount of time to figure this out.

I have no idea what's happening here but I'm using XAMPP and it has the feature to check all open sockets and it's reporting here

that despite my ssh config being set to 0.0.0.0, it only binds to localhost (aka 127.0.0.1)
