Couldn't sign in to microsoft account [Error code: GlowStone]

Hi?

I had been playing with minecraft(android) by logging in my xbox live ID.
But, suddenly minecraft reports below error when I logged in xbox live ID and select "play".

"We could not sign you in to your microsoft account. Access to Realms, Profiles and your Marketplace Items will be limited. Please try again later.

Error code: GlowStone." => attached image file

What's wrong with MY ID? Please correct my problem ASAP.

 

Thanks for your support in advance.
