I have exactly the same problem.
I guess the problem is they create the db users on a server and then assign the DB space to another server, so you have got a valid user on an invalid server:
No pg_hba.conf entry for host 194.106.33.56, user XXXX, database XXXX
Here we see our scripts are hosted on 194.106.33.56, and the PostgreSQL server is running on a different iron.
It's a very easy to solve problem ! Are they all dead ????
