Managed to add dealer locator manually, but still concerned why I cant access the marketplace, when I have another site using C5 using it fine! Although this site is with the same hosting company it on a different server.
This is what they have sent me.
The IP addressed which is used is the web server IP address and that is: 126.96.36.199
Please note, when you contact them then also ask if the script attempts a loopback connection over HTTP, (connection to self), as this will fail because we do not allow loopback connections to be made on our servers.
We've been sorting this out over email, but if anyone stumbles upon this thread in the future, our curl requests don't loop back in the way Simon's host described. We'll check that IP to make sure it's not on our provider's blacklist and let you know what we find.
