Connection problem on the companion web application

When I try to log in to the web application, I get this error message after entering my email address and password:

We're currently having trouble with login services . While we work on it, you can try to log in from your Console or PC to get the full Football Ultimate Team experience 

I have already enabled and disabled two-factor authentication, and tried pretty much everything that chat support could do, but they don't know what the problem is.  As for the game on Xbox, it works fine.

Can you help me please ?
