I couldnt log into my xbox account, did all troubleshooting except for adding and removing ccount, but now that i have removed it, i cant add it back.

Question

I wanted to play some games, but i got an error code like 0x007003b and couldnt log in. I looked this error code up and did all troublshooting. There was make sure connection is stable, update, make it your home xbox type stuff. I saw at the bottom that remving and adding profile back helped some people. I tried it and now i cant add my profile back. I enter my email and the popupp goes away but my account is not added back to the my profiles
