I am running jupyter lab on a remote server (Ubuntu 20.04.5 LTS) and connecting to the server with a local computer. I have two local computers that I use to connect to the server.

- iMac 2019 i7 running Sonoma 14.3
- MacBook Air M1 running Sonoma 14.2.1  
(both using Google Chrome)

When I try to connect to the server with the iMac, jupyter lab tries to connect to a kernel and gets stuck in a loop, repeatedly printing this to the command line:

On the web page, I get an error pop up that says Error Starting Kernel: missing id.  
When I try to connect with the MacBook air, it works correctly.

I have tried a fresh install of python/jupyter/etc, deleting the .jupyter/lab/workspaces directory, clearing browser cache, using different browsers, with no luck.

Package Versions:

- python : 3.12.1
- jupyterlab 4.1.1
- ipykernel 6.29.2
- ipython 8.21.0

Any ideas what might be causing this?
