Error logging into Microsoft account in Minecraft.

I don't speak English, but here goes. My Minecraft won't log into my Microsoft account. I enter the correct information, but even so, when I try to log into Minecraft, it simply doesn't log into the account. I've already tried remote connection, uninstalled and cleared the app's data and cache, and tried logging in using Xbox or connecting through the Xbox Live website, but it simply won't log into Minecraft. I play on my phone, an Android A16, and I'm only experiencing this problem now. 

Obs: Months ago I downloaded Minecraft and it worked fine, but now it's having this error.
