I've been trying to rollout the GlobalProtect VPN software to our end-users and after verifying them as a user and getting the software installed, whenever I go to connect, it attempts to connect for a few seconds and then says "Not Connected." When I look in the Admin section, they show as being active and I turned the firewall off, but that doesn't work, either. I am able to connect with my own computer and have ensured the right domain name is entered.
The issues seems to be from the VPN configuration part. Please refer to this guide for more details: https://help.okta.com/en/prod/Content/Topics/integrations/palo-alto-radius-intg.htm?Highlight=palo%20alto
For more assistance, we would recommend that you open a suppor ticket with our team, so we can jump on a screen-share and verify the configuration as a whole.
