There are currently disruptions to RWTH Single Sign-On. After entering your login details, the screen loads and then an Internal Server Error appears. This affects all services that use the RWTH Single Sign-On login.
The specialist department has been informed and is working to resolve the issue.

The problem has been fixed.

During this period, the routing of the previous XWiN routers (Nexus 7700) will be switched to the new XWiN routers (Catalyst 9600). These routers are essential for RWTH's network connection. This changeover also requires the migration of the DFN connection, which is switched redundantly to Frankfurt and Hannover, and the RWTH firewall to the new systems.
There will be complete or partial outages of the external connection during the maintenance window. All RWTH services (e.g. VPN, email, RWTHonline, RWTHmoodle) will not be available during this period. The accessibility of services within the RWTH network will be temporarily unavailable due to limited DNS functionality.

Der Uplink nach Frankfurt wurde erfolgreich auf das neue System geschwenkt.

Umbau des Uplinks nach Hannover beginnt.

Uplink nach Hannover auf das neue System umgezogen.

BGP v4/v6 nach Frankfurt und Hannover sind nun über die neue Routern funktional.

Es stehen noch ein paar kleinere Nacharbeiten an.

Wartung ist abgeschlossen. Der Datenverkehr läuft nun vollständig über die neuen Router!

Problematik mit der Anbindung zur Physik identifiziert, Lösung erfolgt morgen früh.

RWTHblog is currently not available.
The responsible department has been informed and is working on a solution.

The problem has been fixed.

This evening around 20:25 - 21:00 there was a performance low in the SSO service and was checked by the specialist department during this time. The problem has been solved and fast logins without waiting times are possible again.

For a short period of time, there was an error while using RWTH Single Sign-On.
The problem has been solved.

Due to the expired certificate for idm.rwth-aachen.de, no IdM applications and the applications that use RWTH Single Sign-On can be accessed.
We are working on a solution.
- An insecure connection message is displayed when calling up IdM applications.
- When calling up applications with access via RWTH Single Sign-On, a message about missing authorisations is displayed.

The certificate has been updated and the applications can be accessed again. Please delete the browser cache before accessing the pages again.

Due to DNS disruption, the name servers of various providers are currently not returning an IP address for hosts under *.rwth-aachen.de.
As a workaround, you can store alternative DNS servers in your connection settings, e.g. the Level3-Nameserver (4.2.2.2 and 4.2.2.1) or Comodo (8.26.56.26 und 8.20.247.20). It may also be possible to reach the RWTH VPN server, in which case please use VPN.

Instructions for configuring an alternative DNS server under Windows can be found via the following links:

You can also use VPN as an alternative. If you cannot reach the VPN server, you can adjust the host file under Windows according to the following instructions. This will allow you to reach the server vpn.rwth-aachen.de. To do this, the following entry must be added:
134.130.5.231 vpn.rwth-aachen.de

The hosts of RWTH Aachen University can now be reached again from outside the RWTH network.

Individual users may have experienced problems even after the fault was rectified on 25 August at 9 pm. On 26.8. at 9 a.m. all follow-up work was completed, so there should be no further problems.

Since July 2, 2024, the RWTH Single Sign-On (SSO) and the login of all SSO-connected services is protected with multifactor-authentication (MFA). In addition to an individual password, users must now enter a second factor when logging in. The second factor must be generated in Selfservice [1] via the Token Manager. Further information can be found on IT Center Help [2] and the IT Center Blog [3].

Unfortunately, the login via the RWTH Single Sign-On and thus into the connected services is currently only successful in individual cases.
If you receive an error message, please try to log in again in about an hour.
People who are already successfully logged in are not affected by the disruption.

The servers are currently at full capacity. We therefore ask you to try to log in at a later time (approx. in one hour). We are working on a solution to the problem.

Through various measures, which have significantly increased the overall performance of the servers, the loading difficulties and login problems were resolved around 3 pm.
For the time being, the message remains as a note, as we continue to monitor the load on the system.

The login to the RWTH Single Sign-On is stabilized. For this reason, we are ending this notice.
