• PAN OS 10.2.0 and above. 
• Global Protect portal and gateway configured with User/UserGroup Config Selection Criteria.

• This could happen when Global Protect portal is configured with User/User group. 

1. The workaround for the issue is to remove any user or group configured under portal Config Selection Criteria.
2. Go to Network > GlobalProtect Portal > Agent > Config > Config Selection Criteria and remove the user or groups called.
