Signing Into Xbox Live Does Not Work and is Needed For Servers

I really want to play on my servers, especially the ones that I purchased ranks on. I cannot do that because I need to sign into Xbox Live to do so. I will provide I file to show you the bug that I am about to explain. So basically, I click the "Sign In" button in gray, located in the bottom left corner of the home screen. After I click it, it shows a little pop-up that says, "We are connecting to Xbox Live to sign you into your account." Then, A green page (Xbox) comes up for a second with a loading circle and loads for about a second or two. It then glitches to the home screen and nothing happened. I tried again and still doesn't work. I hope you have a solution to this bug because I had so much fun on servers and Windows 10 Minecraft until the update arrived.
Thanks for your time,
Andy
