This helped 
(a first only cleared my cache)

Update:

After some more testing it seems that only chrome has the problem.

The app and Internet explorer still work.

Hi,

when I'm trying to login this refreshes but doesn't log me in.
I tried with a wrong password and then I get the message of wrong password so I'm sure I use the right credentials.

I also tried on my phone and have the same problem there.
