Hi Tom,

quoting the IPv6 address resolved the issue!
The error message is far away from being helpful. )-:

Thanks for your patience,

Oddly SSL6ServerEndpoint doesn't exist, though, and I don't see a generic server wrapper like wrapClientTLS <https://twistedmatrix.com/documents/current/api/twisted.internet.endpoints.html#wrapClientTLS> for the server site. I'm afraid I may have led you down the wrong path --- I didn't realize this was missing.
