SSL/HTTPS Webmail (odd) issue in General Discussion Posted September 25, 2017 · Report reply Thanks d00p. That has now sorted it. If anyone else comes across this problem where webmail was either not working or only working for some, hopefully this will help. The server was migrated from one service provider to another. There was a line in the Froxlor config, Resources > Ips and Ports > x.x.x.x:443 that was Alias /webmail /var/lib/roundcube Once this was removed, webmail starting working properly. The reason it was working for some and not all is that on the old platform it did not have IPV6 hence on the new platform it was fresh and working fine.
