Failed to connect to the remote jupyter server

[xwshen51]

I have submitted a batch job to launch jupyter lab on cluster, but when I copy the url to vscode jupyter server, the following error appears and I am not able to connect. Could anyone please offer me some advice? Thanks in advance.

Most likely a duplicate of #13000 (comment)

See this for a temporary work around #13000 (comment)

thanks for your reply! but I dont think that’s the same issue and my problem still exists.

[DonJayamanne]

I'm sorry that does not work, please could you describe the steps you have taken to repro this issue.
Also, does the Jupyter server require a password for authentication?

Attempt to upgrade your Jupyter notebook package. It worked for me!
