Remote-SSH: Connection to Cursor server failed: Failed to install server within the timeout

[jasonbian]

Describe the Bug

When attempting to connect via Anysphere.Remote‑SSH, the install script hangs and eventually terminates due to a timeout. It prompted “Connection to Cursor server failed: Failed to install server within the timeout.” And asked to Reinstall Server or Reload Window. Sometimes it takes a few hours to successfully connect.

When I use VS Code, I can connect to the same server (using same .ssh/config) within 3 mins.

I have attached:

• The output log of Remote - SSH.txt of Cursor
• my settings.json of Cursor is below:

• the successful setup for VS Code is listed. However I have to downgrade VS Code from newest (1.100.3) to version 1.95 to successfully connect to the remote server. (I don’t know why, something related to glibc version). The MS.Remote-SSH is version 0.115.1.

Additional Information

Not sure if this is relevant. I also need to switch HTTP2.0 to HTTP1.1 for “Code Indexing” to work.

Does this stop you from using Cursor

Yes - Cursor is unusable
