Julia kernel failed

I’m using JupyterHub and JupyterLab, and I have many kernels (including Python and Julia kernels).

All the other kernels work fine, but when I try to launch the Julia kernel, the kernel status shows “disconnected” and then changed into “No Kernel | Unknown”.

I look into the console of the browser:
failed: WebSocket is closed before the connection is established.

I have another server which has the same OS, same version of jupyterhub==3.1.1, jupyterlab==4.1.6, Julia v1.10.2, and same configurations.

Does anyone have any idea ?
