integration problem

When I activate the membership gateway my client sign up page fails to load

the url that is attempted to be loaded is:
my client signup page:

During the live support yesterday it was suggested that I get an ssl certificate which I did and I have requested and recieved it through my host and godaddy. What else can be causing this issue? Is thier a setting that I need to change in or in membership?

I am getting an unable to load timeout not a 404 redirect.

Any help would be greatly appreciated.
