Yes I am on an rgh. I will try it with xhttp disabled. And i also am using ninja's gold spoofing.Are you on a modded console of some sort? If so, make sure 'xhttp' is disabled in Dashlaunch.
If you are on a retail console, try rebooting your router or resetting your Xbox network settings. You can do this by:
1. Going to your console's network settings.
2. Go into your connections settings. (Press A on your wireless or wired connection)
3. Then go to Configure Network.
4. Scroll across to 'Additional Settings'
5. Click on Restore to Factory Defaults
Please note that the above steps are assuming you are on an Xbox 360 console, it will be similar for Xbox One.
