The problem goes down to wrong DNS configuration.

MySQL client tries to connect to non-existing hostname 'invalid_hostname'. It expects to
get error 2005, which means 'invalid_hostname' can't get resolved. But if it is resolved
MySQL gets error 2003 (Can't connect to MySQL server).

Check
$ host invalid_hostname

If the request is resolved - it is bad.
