Hi Team,

We have ords and apex running on different machines. We are running this instance for last 6 months. All of the sudden, we have this issue when hitting the url.

Service Unavailable HTTP Status Code: 503 Request ID: jGZY_ECWAIgDTO2lly1iIA Request Timestamp: 2025-05-06T11:44:18.679809Z The connection pool named: |default|lo|, encountered an error: mismatch with the server cert DN: IO Error: The Network Adapter could not establish the connection (CONNECTION_ID=zgON6ZYoRq+aptAgoiNWxQ==)

We have added ssl_server_dn_match=no in sqlnet.ora in database server and bouned the listener. It worked for a day. When we bounce the database the next day,it stopped working. We raised SR and we are updated to Add (security=(ssl_server_dn_match=no)) at existing connect string at tnsnames.ora.
