Remote SSH disconnects and cannot reconnect to EC2 instance

[NoopDawg]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I connect to an EC2 instance via the AnySphere Remote Explorer Extension and recently, whenever I get disconnected, the extension is unable to reconnect.

I used to have the ms-vscode-remoteexplorer extension instead and that had a “Kill server on remote” type action that would let me reconnect after killing the server. Now that I switched to Anysphere that option isn’t possible.

I also lose my progress on any files I’m working on. This started today, but I had been using these extensions successfully before today.

Steps to Reproduce

Connect to an instance via Remote Explorer.
Lose connection
Attempt to reconnect to that instance

Expected Behavior

I can reconnect to the EC2 instance

Does this stop you from using Cursor

Yes - Cursor is unusable

Update: I was able to ssh from the terminal and grep the processes for anything with “cursor-server”

After killing those processes, I am able to connect to the instance again.

This is a workaround, but I wouldn’t consider this reasonable, since there are often dozens of these…

It seems that having an existing server is what breaks the reconnection attempt

hi @NoopDawg could you try this with 1.6 that is rolling out now?
