Malfunction when logging into central services
The responsible specialist departments are already looking for the cause and will correct it as soon as they find it.
Login to the various services should work reliably again once the error has been rectified.
Until then, we ask for your patience and, if necessary, for a new connection attempt at a later date.
Update: The problems have been localised and fixed. All services should now be available normally again and it should be possible to register without errors.
