Hello,

i already have a working Mailserver on one of my two Servers.
What i want to achieve is having Roundcube on another Server which connects to the Database of my Mailserver.

But im failing at connecting to the Database of my Mailserver, the only error i could reproduce was this one:
"DB Error: SQLSTATE[HY000] [2003] Can't connect to MySQL server on 'IP HIDDEN' (4)

Thanks in advance.
