Around 8/23/25, I installed macOS 15.6.1 on my work Mac. After this I can no longer log the application I am working on into our backend servers. My work Mac is running Palo Alto Global Protect VPN software along with a bunch of associated security software to lock down my computer. I had no issues with connecting to our backend servers behind the firewall before the macOS update and nothing has changed in the source code related to this. When I send the username the network call just hangs and never times out.
On the other hand, if I turn off the VPN and point to the production environment the call succeeds with no problems.
Any Ideas?
