I think it is the problem.  Try adding -initialtls to inc's options,
either by editing ~/.mh_profile or just temporarily at the command line
where it will augment those in the mh_profile(5).

    inc -initialtls

There are two ways of establishing a TLS connection to a server:

- Immediately after the TCP connection is established.
- After both the TCP connection has been established and some
  unencrypted protocol has been exchanged to request the upgrade to
  encryption using TLS.

I've suggested the first method in the hope your server supports that.
If it doesn't seem to, at least on the port you're trying, then inc has
a -tls option which attempts the second method.

Lastly, there's a -snoop option which may help diagnose how far things
