it is all on the same server round cube php and mysql internally referred to as localhost, so no DNS issues. A Firewall is not activ on the machine.
The Error msg is:
DATABASE ERROR: CONNECTION FAILED!
Unable to connect to the database!
Please contact your server-administrator.
If I look into the config file and use the line with the DB connect in terminal I am able to connect to mysql and look at the DB and the corresponding tables.
Any idea how to trouble shoot would be greatly appreciated.
Best
