aspx and eu

The problem is that the server is trying to call itself (to an aspx page) but it's unable to resolve the .eu domain.
You can add that entry to the hosts file and that way it will work, but the wizard should have suggested that solution.

You don't need to remove anything from the hosts file, only to add the extra entry, that way it should be able to resolve the new domain. The error message doesn't provide any extra info? if you don't want to post it here, send me a Personal Message with all the details about the last test
