Xbox live got removed from my account

I only have one email that i use for xbox so theres no possible way it could be on a different account.

Nothing shows up under subscriptions when I click that link.

In that case, you have no Gold subscription on that account. You need to check on which email you added the Gold subscription.

I have the 12 month membership that renews automatically. And it doesnt show up anymore. I also cant check the subscriptions.

Is it possible that you used someone else's Gold membership that was shared by your console via the "Home Console" feature?

If someone else with a Gold membership signs in on your console, and plays with you, or even sets your console as their Home Console, the console will share that account's Gold membership to everyone playing on that console.

So you could be able to play online Multiplayer without having a Gold membership, and after you factory reset the console, that Home Console assignment was removed. In that case you'll have to ask the owner of the Gold membership to set your console as their
Home Console again. (Beware however, that there is a limit of 5 Home Console settings per account per year)

If you are sure you paid for a Gold membership, do as WPAK suggested and check on

Gold memberships are tied to the account they were redeemed/bought on. So if you used a different email to buy the Gold membership, make sure you are using that very same email account to sign in on your Xbox.

Maybe those were the two last seconds you had of xbox live and your membership finished. As mentioned before a factory reset doesn't changes your membership status, so verify when your membership was completed and if you want to continue spring for a method
of payment.
