I tried to configure to have all users restricted on their IP login, but in doing so I caused the browser not to load Roundcube anymore (getting a connection has timed out error). I reset allow_nets to NULL, but still having the issue even after rebooting the server. Not sure what to do at this point. Happy to provide more info if needed.

Update:
Checked the smtp using telnet and had no errors. Still not loading in the browser although I was able to receive emails in /var/vmail/vmail1/..../new/
