More information, even git clone [email protected]:xxx/xxx.git failed, ssh -T [email protected] still work under mirrored network mode.

@Ghost-LZW please post the full output of git clone. Could be a transient connectivity issue. I did a quick test and it seems to work as expected:

zcobol@texas:~$ wslinfo --networking-mode

after close my proxy, git clone get work ..., now the problem becom git clone via vpn work in powershell, but failed in wsl2. sorry for false report, I'll close this issue and check if this issue due to vpn software.

[oldshensheep]

If you are using a VPN, could you try setting the MTU to 1500 in WSL2? The interface should be the VPN's interface.

show interface

ip a 

change MTU

ip link set dev <interface_name> mtu 1500

show interface

ip a 

change MTU

ip link set dev <interface_name> mtu 1500

I do set the MTU as the same as the host value but still does not work.

[oldshensheep]

I have a similar issue, git clone doesn't work, but ping works.

I do set the MTU as the same as the host value but still does not work.

Make sure the interface is VPN not the host's interface and set it in WSL not windows (I have not tested in windows)

You can test whether it's the same issue by using this command.

curl http://google.com --trace - -L

There will be an HTTP 301 redirect to http://www.google.com/. It should hang at this point, as it is sending a large web page. If you don't see the HTTP 301 redirection, this might not be the case.

@oldshensheep Good catch ! Same issue, set mtu to 1500 instead of 9000 helped. I think the upcoming discussion will shift to your open issue.
