Hey there. only access TLS 1.2 and 1.3 connections.

If I’m remembering correctly – IBM’s implementation of Java 8 has TLS v1.2 disabled by default. You can try enabling TLS v1.2 in IBM’s implementation of Java 8 by passing to your iDE. This may require making sure you’re using the latest version of IBM’s Java 8 distribution.
