You applied ePO 5.10 Cumulative Update 11 or later.
Cause
This issue occurs due to a problem with one of the files that controls the cryptography provider used by ePO, which in turn means that ePO doesn't successfully complete a TLS connection. To identify this specific issue, open the ssl.TrustManagerFactory.algorithm=PKIX If you're running CU11 or later and you don't see the above statements in the file, you have the issue addressed by this article. Solution
The steps below can be performed to resolve this issue:
