please retry with a different device or other authentication method to sign in

I can’t log in to my outlook account while connected to my home network, which has the default configurations from my Mexican ISP. I already tried multiple devices connected to the same network. I need to use my cellular data instead., which allows me to log in correctly. I’m not using a vpn or anything like that and it’s been happening since a couple of months ago. This is the message I’m getting:
