Hi Axel,

I'm not entirely sure what's going wrong there (maybe quote the ipv6 add=
ress?), but you want to retain the various independent command-line opti=
ons you should instantiate endpoints directly rather than constructing a=
n endpoint string (the endpoint string is useful to expose *directly* as=
 a CLI parameter).

I.e., you can construct SSL4ServerEndpoint <https://twistedmatrix.com/do=
cuments/current/api/twisted.internet.endpoints.SSL4ServerEndpoint.html> =
directly. Oddly SSL6ServerEndpoint doesn't exist, though, and I don't se=
e a generic server wrapper like wrapClientTLS <https://twistedmatrix.com=
/documents/current/api/twisted.internet.endpoints.html#wrapClientTLS> fo=
r the server site. I'm afraid I may have led you down the wrong path ---=
 I didn't realize this was missing.
