Globalprotect tries to connect then goes back to 'Connect' button

Having one computer that has issues with the GP client. I have tried GP version 4.8, 5.2, and 6.1 and various means of having them update or refusing to update etc.  I have restarted the computer, uninstalled and deleted app data and Program Files folders. Removed every trace of registry entries. Etc etc

This single computer just will not connect. Now, if I install 4.8 it will connect, say it needs to upgrade and download 6.1 and install but after that it will not connect.  I do not understand where the disconnect is with this one computer.

Also.. even after removing all appdata/program files/registry, when re-installed GP still retained the SAML login info. Something I'm missing?

I don't want to swamp the post in logs but if someone wants one in particular to help, let me know.

Thanks in advance.

wouldn't hur to take a look at the logs...   try to connect at an exact time..... then just post the "pangps" file content from that time onwards.

Thanks for responding.  In the end we re-imaged the machine and that fixed it.
