What does ‘Schnittstelle nicht offen’ (interface not open) mean?

If the Studierenden-Online-Funktion online tool system is overloaded, you will experience long waiting times and the error message "Interface not open" is sometimes displayed. If this message is displayed you should log out of the system straight away and continue your examination registration at a later time.

You should never interrupt actions that take some time or restart or frequently update the pages displayed, as this overloads the system.

If you have problems that need urgent attention, contact the relevant Examination Office.
