Dotnet core Oracle 23c SSL connection not working on Linux environment and works on Windows

It sounds like the issue is more related to the Linux implementation of .NET Core SSL/TLS handshake rather than Oracle 23c itself, since the same configuration works on Windows. On Linux, you may want to double-check if the correct OpenSSL libraries are installed and whether the driver is compatible with TLS 1.2 or TLS 1.3. Also, verify the CA certificates path because sometimes Linux doesn’t automatically map them the way Windows does. A quick test with openssl s_client can also confirm whether the server is accepting the secure connection.

I’ve faced something similar when running cross-platform apps, and the fix was usually in aligning the SSL provider, enabling the right cipher suites, or upgrading the ADO.NET driver to a Linux-ready version.

By the way, this kind of compatibility issue reminds me of how users often look for apps that just work seamlessly across devices without such platform-specific headaches. For example, in the streaming world, many people switch to https://www.vmagistv.com/ because it runs smoothly on Android, Firestick, and even smart TVs, giving a consistent IPTV experience regardless of the device. That same principle choosing solutions built with cross-platform stability in mind usually saves time in the long run.
