TCPS connection not working on linux bot works on windows

David KovacMar 14 2024

I'm using Oracle.ManagedDataAccess.Core v3.21.130 in .Net 6 application. I'm trying to connect to Oracle DB 19c hosted in AWS RDS using TCPS. I'm using oracle wallet configured in sqlnet.ora. Everything works on Windows, but on linux (ubuntu) I'm always getting

ORA-00542: Failure during SSL handshake
System.Security.Authentication.AuthenticationException: The remote certificate was rejected by the provided RemoteCertificateValidationCallback

when opening connection with no additional information in trace.

The database is configured to allow TLS 1.2 with ciphersuite TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384.

Does Oracle.ManagedDataAccess.Core not support TCPS on linux ?
