Jupyter Notebook via SSH break with latest update

[poolsar42]

Describe the Bug

Hello everyone. I updated cursor on July 23 and after that was not able to open .ipynb file on remote server to which I sshed.

Could you give some hints on how to fix that? I was able to open .ipynb files before, I reinstalled all jupyter extensions on the server, but issue persists.

On the positive side, I am still able to open .ipynb files locally.

Steps to Reproduce

1. SSH to any server
2. Download Jupyter extension from ms-toolsai
3. Create .ipynb file and try to open it

Doesn’t work for me

Expected Behavior

.ipynb file should be viewable.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi @poolsar42 , what is the error when you click the “enable extension” button?

[poolsar42]

Howdy @ravirahman

It shows no error - it just closes .ipynb file.

Hi @poolsar42, could you close the editor, and then open a terminal run rm -rf ~/.cursor ~/.cursor-server directories on your remote machine? This will wipe all state, including all extensions on the remote host and remote-specific settings.

It helped, thank you.

@ravirahman It does not work for me. Instead of SSH, I have a docker container running.
This issue persists even after removing cursor server, extensions, etc. (on docker terminal outside of Cursor)
