Update version mismatch on HA

Hello guys, I have a pair of fw on HA an I got a version mistmatch after last update.

Unfortunately I have an issue getting the 2 devices to sync. I am seeing an issue getting updates (software/dynamic) from palo alto updater. I'm getting the following error:


ERROR: "Failed to check upgrade info due to Unsupported protocol. Please check network connectivity and try again."

I have the version mismatch on the followings:

App Version Mismatch

Threat Version Mismatch

Antivirus Version Mismatch


Has someone faced and resolved this issue?

Yeah! Unsupported protocol was weird to me as well, I found the resolution, this was made to resolved the issue:

> Management interface was configured under service route for palo alto network services.

> DNS was getting resolved without any issues.

> Initiated a ping from management interface to "updates.paloaltonetworks.com" and found that there were DUP ping responses received.

> We then initiated another ping from DP untrust interface and no DUP ping respones seen.

> Changed the service route to use eth1/1.900 and that fixed the issue.

> Need to do the same change on Secondary device too.


Thanks for your anwser :)
