problem connecting to ssh. While ssh works properly on terminal

[abhilashreddyy]

Issue Type: Bug

I am getting this error while trying to connec to my remor\te GCP VM. ERROR : Failed to connect to the remote extension host server (Error: Cannot read properties of undefined (reading 'replace'))

This don't happend immediately after creating a ssh in ~/.ssh/config. But after sometime like a day or something. I guess it is some kind of cache related issue

[vscodenpa]

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.68.1. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

Could you also share your Remote SSH logs with us? But yes please update first

[abhilashreddyy]

Hey can you tell me how to share the remote SSH logs. I have changed the version to the latest one 1.68.1 as suggested and it was good for some time and then the same error occurred again.

[FYI] if i change the name of the remote ssh then i am able to connect again. However I am loosing all my open files.

This is what I found in the console.

[dbaileycamus]

FWIW - am seeing same problem myself, also on a GCP VM, same intermittency too, and same error on "reading 'replace'".

[eleanorjboyd]

Hello @dbaileycamus and @abhilashreddyy, my name is Eleanor and I'm the new Remote-SSH maintainer! Are you still experiencing this issue on the most recent version on VS Code and the extension? Additionally do you have any firewalls on your server? Sometimes these can interrupt the script transfer.
