How can I unblock my Xbox cloud gaming

first we need to know exactly how the services blocked. Please provide error codes in as much detail as possible

No I never answered my own question. If you read carefully, I said I know what to do to unblock somebody. Then I asked how can I unblock somebody when we've blocked each other? This means I explained that I know how to unblock somebody when he hasn't
blocked me. This means things are harder to deal with when we've blocked each other because if I send him a message, invite or friends request, he won't get either of them so that I can unblock him, same thing visa-versa if he tries to unblock me. I was
asking if there's another way to unblock somebody when he's also blocked me, such as, is there a block list for me to unblock him from or can I unblock him by contacting Xbox Live?

Send a friend request to the player and message to him or her. That should unblock communications with the person.

. She invited me to minecraft and I accidentally blocked her. And every time I try to send her a message or invite it says that this gamertag dose not exist on xbox live. July 17. 22:18.

^^ Maybe he/she blocked you too?
