Hello good evening, this happens to you, of the Global Protect access problem, does it happen only from that endpoint ? did you try from another endpoint and validate whether or not you can connect to GP.
Now you have and/or you have the Global Protect license to allow access from a Linux device ( You indicate Ubuntu 22.04.1 LTS ).
Check this link and you will see that for mobile devices, to use GP from Linux, you need an additional subscription/license.
