Global Protect disconnect issue

L3 Networker

3000 series FW, software 6.0.1, GP 2.0.1 -- GP continually disconnects/reconnects.. tried reinstalling client, rebooting, etc.. happens with some users at random times..then the issue will magically go away.  Anyone else experience?

Hello Rrau,

Could you please confirm the internet connectivity from the affected machine during the issue. More more detail info, you may enable logging into the GP client:

---Advanced view > Troubleshooting tab: start

debug on PanGP Service

File > Collect Log

c:\Users: look for Pan… files

---Wireshark on client PC

Reference DOC: Troubleshooting GlobalProtect, PAN-OS 4.1


Def has nothing to do with the local Internet service.  Happens at random intervals with random machines in random locations Smiley Happy

I will run debug on a client machine next time I see the issue.  thanks!

We are seeing the issue as well.  In the GP logs we are seeing:

Each time we get a disconnect.   Engineering is looking at it.   I will post when they figure it out

What was the solution for this? I have couple of users complaining about the same. It disconnects randomly and restablishes the connection. 

I believe the internet connectivity is fine since we are all in the same network but for some reason only selected couple of users have this issue. I was looking at the logs and found this during the same time frame.
