I don't know if this is relevant, but I am curious if there may be a
difference from using the ip:
ssh -v -p 443 dion@127.0.0.1
or the host name:
ssh -v -p 443 dion@localhost
on your machine? Sometimes the ip and host names are treated differently.
I have run into this on more than one occasion. Sometimes it can be
firewall rules related.
