Just found the issue in my case guys. I was trying to access a database which was in a different instance of the regular one and it seems that this is not possible, so when I tried a database in the default MSSQL instance, it worked.
Was working with the change to master database, because it existis in both instances.
There is workaround for that, but does not make sense in my case MSSQL Datasource: Connection to Named Instance not working
