Hello!

After Centos upgrade from 6.0 to 6.5 and Zimbra upgrade from 7.2 to 8.0.6, I have issues with loading the Zimbra interface (admin as well the user).
I have noticed that jetty is not able to connect to the database according to this log file /opt/zimbra/log/jetty.log .
As you can see bellow I have : UnknownHostException: address=(protocol=tcp)(host=)(port=7306) , again host='' and I think this might be the problem.
I would appreciate any suggestions!
