GlobalProtect has DNS issues after waking from sleep mode

L2 Linker

GlobalProtect on Windows.  User locks computer and computer goes to sleep. They return and unlock.   If GlobalProtect has disconnected while in sleep mode, they user reconnects succsfully.  User's drive mapping fail and apps fail.  Pings name of server and that fails.  PIngs IP address of server succeeds.  Restarts PC and everything is fine again.

 

Whats going on?

What version of client do you have.  When device wakes from sleep mode or switches from lan to wifi the client tries to reconnect to the previous gateway and some routing/domain issues seem to take place.

 

the same issue applies when using domain split tunnel exclusions.

 

have you tried a GP refresh before a reboot, are you above V5.1.

We have 5.2.9 , we have tried GP refresh connection, it sometimes fixes the issue but ideally we want the GP to restore connection after sleep without user having to refresh/reboot.

 

What is the fix for the issue you mentioned?

@HoomanF,

You shouldn't be running into any issues with 5.2.9. I would recommend that you look at your client logs on an endpoint and see if they give you any clear errors in addition to checking your traffic logs and see if you have any traffic being received by the firewall. 

I am running into identical issues with GP client versions 5.2.8 - 5.2.10 and the latest 6.0.  It seems to be DNS related as it also shows that we are running from a "cached profile" where before it would show portal gateways as "connected".  We haven't changed our configurations in regards to pre-login and always-on for at least a year and a half and we have double and triple checked our configs (we have a ticket open with TAC on this now), we have split tunneled the portal/gateway IP addresses and domains), and just noticed the reconnect and portal cache issues recently (last 3-4 months).

 

If anyone found a fix for this please share.
