Cannot authentication to WSS Agent via popup after MacOS host wakes up from sleep

User running WSS Agent on MacOS cannot browse internet when the host wakes up from sleep.
Once we hit this condition, even initiating a RECONNECT fails to allow users browse internet.
Logs show that WSS agent tries to authenticate but user never see any popup appear on the host.
PAC file pushed out to WSS Agent hosts to send traffic to local proxy as well as into WSS.



MacOS 12.4.

WSS Agent 8.1.1.


Upgrade to MacOS 12.5 addressed the issue.

It is also recommended that hosts running WSS Agent on MacOS with SAML also upgrade to WSS Agent version 8.1.2.

Additional Information

In terms of log analysis, Webkit never starts the auth process and here are the key log entries:
