Unable to pass Database Configuration step in installer

Hi Helder, 

Assuming the DB is accessible and host and credentials are correct, can you confirm if the right database version is used?

There are also vagrant stacks available here that do all the legwork for the environment setup:

Let me know if that was the case. 

Thanks!

You use the external hostname which is normally not granted by the database. I suppose you should use localhost for the database hostname.
