Helium Console: Unable to log in, please contact the admin

Hello, since yesterday I can no longer log into the Helium Console on the PC. I always get the error message:

Unable to log in, please contact the admin

What am I doing wrong? Does anyone know a solution to the problem?
I use Windows 10 and Firefox browser.
It works on mobile.

Thanks

Erledigt. Wahrscheinlich mal wieder eine Störung bei Helium
