I think I figured out the problem.
1) You have the server set to: http://www.omagonline.com/ but the server has an automatic redirect to: http://omagonline.com/
Try setting the Web URL for the testing server to just: http://omagonline.com/
2) You have included a port number in your connection server. Try removing that as well.
When I made those two changes I was able to connect to your database and see the tables.
