Slack hooks server certificate invalid

L2 Linker

Our firewalls cannot send to hooks.slack.com since they refreshed their cert yesterday (3/14/2023).

 

I suspect a problem with the way their chain is signing X1 root CA but until they fix it, is there a way to allow the log forwarding service to ignore the invalid cert and send anyway?  I see a kb article about doing this for decryption profiles, but not sure if it applies here.

 

Also is there any debugging that can be done on the palo to get more specific detail about what its problem is with the cert?

 

Thanks in advance for anyone who can advise.

Hi @EO-AlexJinks 

 

I have been told that the root cause of the issue is resolved in PanOS 10.2 and that fix will not be ported back to earlier 10.x or 9.x PanOS versions.

 

I was provided with a workaround solution that they should be able to provide for you, too.  If your case is not being addressed, you should ask them to use my PAN Support case number 02496793 for reference.
