Problem with Wildfire Registered Server busy or error

[Alpalo]

Hi team,

We have detected loss of connectivity to wildfire, We have followed the following link but the problem persists https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u000000oMCYCA2

Model PA-3220

Version 9.0

Does anybody know what could be happening?

Thanks so much

I have not seen this, but also would not be staying on 9.0 software.  A recommended version is 9.1.12-h3.

This issue started for me this morning.  Also on 9.0 code.  It has been fine until today.  Same Device Not Registered and Server Busy or Error.
