SSH connection breaks immediately #4924

Dupe Check

Describe the bug

When I SSH into an instance; amazon linux 2023, ubuntu 20.04, and ubuntu 22.04, the connection breaks immediately after entering a command in the terminal. Warp shows the below output after entering any command in the remote terminal

exit
Connection to 10.x.x.x closed.

The issue is almost intermittent, but consistent. Every so often Warp will work as expected but more often than not, the connection will break immediately. I am on an internal VPN, however any other terminal will work including Terminator and the stock Terminal.

To reproduce

  1. SSH to a remote instance in AWS
  2. Enter a command

Expected behavior

I should be able to use the remote terminal/SSH connection as normal

Does this block you from using Warp daily?

Yes, this issue prevents me from using Warp daily.

Is this a Warp specific issue? (i.e. does it happen in Terminal, iTerm, Kitty, etc.)

Yes, this I confirmed this only happens in Warp, not other terminals.

Thanks for reporting. Are you able to try SSHing into a remote instance while not on the VPN, I'm curious if that works.

As a workaround, you can try using adding command ssh to your Settings > Subshell menu, then use command ssh <user@server> to connect to sessions, this will enable Warp features with the subshell method instead of the ssh wrapper.

Or, you can also try disabling the SSH wrapper by navigating to Settings > Features. Blocks will stop working but with it disabling, SSH should work as normal.
