Registration and views for Master's courses taken in advance are sometimes unavailable

Partial Outage
Fri 07/17/2026 03:37 PM - Unknown

Currently, isolated issues may occur with Master's courses taken in advance when registering for courses, exams and accessing views there.
Staff and students have reported that the course selection or the analysis view for Master's courses taken in advance is not loading. In addition, registrations could not be completed.

These issues have already been investigated and reported to the system provider. We hope they will be resolved shortly.

Note for Students:
If registration deadlines are approaching and you encounter error messages, please contact the RWTHonline Support via the support form with a screenshot of the error before the deadline expires:
