Hi,
suddenly we are getting a "connection failed" message from the GlobalProtect Client while using the sectigo wildcard certificate in the TLS Profile of the NGFW.
The traffic logs show a 'decrypt-error'.
There is no decryption policy being used.
We are on PanOS 9.0.7.
It's a bit strange because everything worked just fine until now and there weren't any changes made.
Could that refer to the known sectigo certificate problem?
Is there maybe a fix for this?
Best regards,
Marc

Generate a new certificate for use with GlobalProtect would really be my answer to this question. You should be able to get your wildcard certificate re-issued without the cross-signing between AddTrust and USERTrust and just have USERTrust in the chain, which would a fully valid certificate.

The firewall decrypts parts of GlobalProtect traffic regardless of what you have configured in your decryption rule base, and if you are using a Sectigo certificate which is cross-signed with AddTrust and UserTrust then your certificate would have been invalidated as far as the firewall is concerned on the 30th.

Hi,
I see. Thank you very much for your fast answer.
Is there any way around this?
I assume there are several users with the same problem at this time.

Hello,
Did you manage to solve the problem, I have a similar error.
This occurs after migrating from Windows 10 to Windows 11.
Thanks for any help you can provide me.
