The below error is presented when a CR patch is applied on CA API Portal 3.5
ERROR (SimpleThreadPoolWorker-5:) - [LRSWrapper general] -- javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
Release : 3.5
Component : API PORTAL
It appears that the upgrade changed which ciphers the API Portal was presenting, hence enabling those particular ciphers or all ciphers on the API Gateway will resolve the issue.
NOTE: CA API Portal 3.5 is now EOS. Please upgrade to version 4.5 or 5.0 as soon as possible.
