Cannot login to Xbox Live through MCPE even though I can login at xbox.com

This issue may get removed due to duplication, but no one seems to have issue of just not being able to sign into Xbox Live at all. Some people can sign in once and have trouble the second time, but I can't seem to get it the first time.

Steps to Reproduce
1.Go into Minecraft PE
2.Try to sign in

It will take you to the page and allow you to try and login, but when you input your credentials and press login it gives you the error shown.

This glitch occurred when connected to WiFi and I went to Xbox.com and logged in with no trouble at all
