Intermittent connection issue after upgrade to 9.1.14

Nischal — Mon, 30 May 2022 05:06:50 GMT

Anyone out there facing issue with LSVPN connection after upgrading to 9.1.14?

After upgrading gateway firewall to 9.1.14 , all satellite offices to the gateway are reporting intermittent connectivity.

I don't see any issue with LSVPN tunnel between sat and gw but connection to internal network drop in a specific pattern.

I believe its a bug and has open a case with PA support since it has only been a week this code is out.

Hi @Nischal ,

Have you seen this link -> https://live.paloaltonetworks.com/t5/customer-resources/support-pan-os-software-release-guidance/ta-p/258304. PAN-OS 9.1.13-h3 is the preferred release right now. I would stick with it.

Thanks,

Tom

Well our GP clients to same gateway are not facing issue but all satellite office to same gateway are facing this issue.

Post changing tunnel monitor profile from custom (fail-over) to default (wait-recover) helped stabilize the LSVPN connection.

Strangely the tunnel monitor didn't show going down.

PAN-187151 is fixed both in 9.1.13h3 and 9.1.14 but seems somehow its not yet fixed in these codes.

Ticket opened with PA support , waiting for their update

We reverted to 9.1.13-H3 and the problems were resolved, not sure what's up with 9.1.14 we upgraded last Friday and the problems started this afternoon at 2:30PM and impacted both IPSEC connections and global protect.

Thank you for pointing us in the right direction, we were contemplating reverting back but this sealed the deal and reverting resolved all of our issues.
