Plesk don't run the web interface because it redirects to 127.0.0.1

Question

I'm having a very strange problem with plesk 10.4.4 in a Ubuntu server. It's when i point in the browser the hostname with https: and port 8443 it redirects me auto to https://127.0.0.1/relay. Why that happens and someone knows how to fix it? Of corse since that's a localhost IP it gives page not found and i can't login in plesk anymore...
