Certificate error connecting to PAN UI after mac os catalina update

L2 Linker

I am sure everyone who upgraded to catalina has this issue.

Apple has pushed out new certificate requirements


Not sure about other parameters, but my pan device is serving a certificate that is valid for 10 years (greater than the 825 days accepted by macOS). And i can't override the certificate error anyway.

Question for community is, has anyone here found a solution to the problem?

The obvious answer is to just generate a new GUI certificate and actually have it follow Apple's guidelines. Are you sure that you are hitting the 825 limit though, what is the notbefore date on the certificate?
