1. Check to see which certificate profile is listed under Templates > Network > GlobalProtect > Gateways > your-gateway > Authentication > Server Authentication
2. Find this profile under Templates > Device > Certificate Management > SSL/TLS Service Profile and take note of which certificate is used.
3. Find this certificate under Templates > Device > Certificate Management > Certificates
   1. Check that CN of the subject matches the gateway address specified in the portal configuration under Templates > Network > GlobalProtect > Portals > your-portal > Agent > your-agent-config > External (or Internal) > External Gateways
   2. Check that today's date does not fall outside the Not Valid Before/After dates (also check that system time on the GP client machine is correct.

If everything looks good, try exporting your logs from the GlobalProtect client, and looking at PanGPS.log for clues.
