43:580 portal status is Using cached portal config.

• GlobalProtect(GP) App
• Version 6.1.2 and below 
• Version 6.0.7 and below

• When GP Portal is not reachable during initial connection, the client uses cached config.
• This is indicated in the message  "Using cached config".
• Since the portal is not reachable, the transparent upgrade cannot be initiated.
• When the portal is back online, still the upgrade is not initiated as the portal status is decided by the initial portal connection.

1. The issue is fixed under GPC-16267 in versions 6.0.7 and 6.1.2.
2. Upgrade to the above versions or higher will resolve the issue.
