Vscode-remote-release: Cannot establish a connection to ssh (Maybe incompatible with vscode 1.43.0)

[fuzihaofzh]

After I upgrade the vscode to 1.43.0, I fail to connect to my remote server. I downgrade the vscode version to 1.42.1, it works well. I think this is caused by the incompatibility of the new vscode(1.43.0). Could you please help to update this extension?

Does this issue occur when you try this locally?: Yes
Does this issue occur when you try this locally and all extensions are disabled?: Yes

Same issue here. Workaround:

1. Uninstall the "Remote Development" extension, and all related extensions from the pack
2. Disable auto-updates in VSCode user preferences (I set it to "manual")
3. Remove VSCode 1.43
4. Download VSCode 1.42.1 (the January release) here
5. Install "Remote Development" plugin

Same problem...seems to have been introduced in 0.50. Doesn’t affect all servers (google cloud server is fine, local server fails).

Alternative workaround that fixed it for me:

• click ‘extensions’
• click the cog icon next to ‘Remote - SSH’
• choose ‘Install another version’
• select version 0.49.0

this worked just fine, thank you.

@colonelsammy thanks much, that worked like a charm.

For anyone else trying this:
When I performed the steps listed above I needed to 1 - restart VS Code (this is indicated in the IDE in an obvious way) and 2 - (if using a key) when I first attempted to connect to the ssh client I was prompted for a password one more time...after hitting _Esc_ Vs Code successfully used the key.

I may have been an odd case because I was messing with my ssh config and settings pretty heavily yesterday looking for a fix without rolling back .

This looks like https://github.com/microsoft/vscode-remote-release/issues/2509. Sorry for the trouble.
