Thanks for filling this issue and sorry you are running into this

Please can you provide a screenshot of the problem
Can you also enable verbose logging for jupyterhub from the settings and replicate the issue again
Then provide the output from the jupyterhub output panel

[snami100]

I don't have the admin rights for this JupyterHub. On older versions i could connect, only on the newer version it was not possible.

@snami100 Thanks for the logs and the screenshots.
Based on the logs, it seems the certificate is not valid. I.e. the certificate used by the JupyterHub server
Is this some self signed certificate or the like?

I've got a PR that would prompt the user to allow using such un'trusted certificates (but this is not recommended).
However we have run into this in the past where users use self signed certificates, expired certifidates or the like like.

Please can you

• Download the following file
• Extract it
• Go into VS Code and select Extensions: Install from VSIX
• When prompted, please reload VS Code
• Try this new extension and let me know how things go

If it works great, you can keep using this.
I will ship a pre-release version of this extension once its merged into the main branch and will ship a new version in a week or two, along with the latest version of VS Code.
