This error would surprise me a lot.  None(!) of the unix web browsers
run by normal users are able(!) to use a source port of 443, as it is 
a privileged port only root can use.

Now, that error message with "... to allow SSL request *to* this port."
is fairly typical if you try to use a proxy to CONNECT to a port 22
etc. (non-SSL ports).

USENET is *not* the non-clickable part of WWW!
