Hi,

Are you using the same Python server instance for plaintext and SSL/TLS? Don't you also have to configure the Python server to use TLS?

Okay, that seems to be a user-error and I am assuming you can take care of it.

I think that is a problem with keys-certificate of SSL/TLS

This message tells you the root cause:

Caused by: java.security.cert.CertificateException: No subject alternative names present

Your server certificate needs to have a SAN (subject alternative name) - or CN - that matches the server identity (either hostname or IP).  You can read up more here https://www.rfc-editor.org/rfc/rfc6125#section-6.4
