I cant play minecraft bedrock servers. it says sorry, we failed to validate your login

That most likely the issue here. It's actually against the Microsoft's Terms of Service using illegally acquired games or licenses. If that's the case, I am afraid that here in forum and even on their game support, we cannot further assist you on this issue.

. im using windows 10. i also tried it on a different device. also, im playing cracked minecraft bedrock

Hi there! Sorry to hear about what happened. Let's do our best now to get this sorted out.

What exactly is the device/platform are you using to play the game?

Please try to simply sign out your account from the game and sign in again. If you have a different network connection, please connect it to a different one - you could use mobile data or mobile hotspot.

by the way, is it happening because i use cracked minecraft?

I appreciate your efforts there. It seems to be a server-side issue from Minecraft. I recommend that you directly contact the Minecraft team by submitting a ticket here https://help.minecraft.net/hc/en-us/request/new for them to further investigate your issue.
