Renewed & Overwritten certificate not being used by some clients
We renewed our primary SSL Certificate for the bulk of our SSL Profiles and overwrote the existing cert (which was expiring). In our testing, we see most of our internal clients using the new certificate, but several external clients are still using the old, expiring certificate. Why wouldn't these clients pick up the new renewed certificate? Why do some clients see the new cert and others do not? How do we force the clients still using the old certificate to switch to the new one? Ideally we do not want to impact existing sessions (do not want to "kick anyone out", ). Thank you for any suggestions.
