Can't login on the website

It's as simple as the title says.

When i try to login, i get redirected to my profile page but i'm not authenticated.
The decrypt page also says i need to login.

Start by reproducing the website login flow described in the issue, checking the redirect to the profile page and the authentication state there. Then check the decrypt page behavior; done means a successful login remains authenticated and the decrypt page no longer reports that login is required.
