I have successfully setup a port forward in my router and was able to successfully login from an external site once but now it won't accept my userid/password anymore. I have tried the following and nothing allows me to login again. I do connect as I get the login banner, but nothing listed below seems to allow me to login again.
Restarted mezzmo service
restarted mezzmo app
changed password for failing userid
tried firefox and chrome.

Any ideas?
