There are other posts and the accepted solution was to use a different cert server, but that doesn’t apply to us. Since it works 99% of the time.
We keep seeing this randomly. I’m lost on how to fix the issue. it resolves over time, but we really need a way to fix this when it happens. Other clients have zero issues connecting and again, it resolves itself over time. I would say it’s almost always Windows that has the issue.

Hi
Do the affected windows machines have the correct time/date when they reject the ISE certificate? If AD joined, they should sync time/date with AD using udp 123 - is this port open for unauthenticated clients?
