Rainloop not working?

Hi,

I’ve set up an email address using email > create email > “mydomain.com

I’ve set up SSL for the mailserver (as well as the normal domain).

When I click email > access webmail, a new tab opens with myipadress:8090/rainloop/index.php

“Not found” - the requested resource was not found on this server.

What do I need to do to activate rainloop? It’s not giving me the login screen to the email service.
