unable to access Palo Alto Web GUI.

L0 Member



After a recent update from 8.1.20 to 9.0.0, we are not able to access the Palo Alto web GUI (hmmm.. can't reach this page)

But we are able to ssh to the device though. We are updating the firmware to the latest version but now need to figure out how to bring up the web gui. 

our device model is pa 3020

any thoughts?


Thank you.

Hi @SIIX_Support ,


Most likely it is an issue with the certificate.  https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000Cli0CAC.  During the configuration conversion from 8.1 to 9.0, the cert or or SSL/TLS profile got corrupted.


Changing the certificate configuration and commiting should automatically restart the management plane.  If it is not a cert issue, maybe the management plane needs to be bounced.  https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClaGCAS


Please let us know if these steps fix the issue.
