I'm using the 3.14.2 module, and also gets this "TLS version is not compatible" message.
But that's not all. When the module is active, I get this "site not secure" and a orange triangle on the lock in the browser. (see attached picture)
I've tested the site at https://www.ssllabs.com/ssltest/, and it runs TLS ver 1.3 and everything else seems OK.
Any suggestions will be of great value. TIA
