I have seen this once before. When i got this error it was a ghost certificate in the ISE certificate store. We had to get TAC to log in to the ISE Linux shell and manually remove it on all nodes in the cluster.
So, unless this certificate is one you expect to be in your ise deployment i would check if its a ghost certificate.
