That you can now successfully get to "localhost" is good progress.
Seems you want to stay away from ipv6 networking issues unless/until
you resolve whatever that issue is.

Roundcube is, potentially, a totally separate issue. I don't use it,
so can only suggest minimal debugging ideas.

What is the hostname that you use to get to your roundcube instance?
Can you resolve that:

   dig <hostname> a

If you get an answer, is the ipnumber correct?

Note, if the hostname for your roundcube instance is one of the ipv6
entries in your /etc/hosts file, I'd remove that - and either put in
an ipv4 entry or put an entry for it in your dns.
