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.

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.

At the moment, single sign-on and multi-factor authentication are sporadically disrupted. We are already working on a solution and ask for your patience.

Due to maintenance work, there may be brief outages.

Due to problems with the load balancers (F5), the majority of services such as RWTHmoodle, RWTH Single Sign-On, RWTH E-Mail etc. and all services behind the RWTH Single Sign-On are disrupted.

A technician from the manufacturer has now also been called in to solve the problem.

The fault has been rectified. However, there may still be delays in delivery or receipt.

Due to database maintenance, login to applications protected by RWTH Single Sign-On (e.g. RWTHonline, RWTHmoodle, Selfservice, SAP) will not be possible for a short time during the specified period.
Please log in to the application in which you would like to work during this period before the maintenance.
We assume that the interruption of the login will last about five minutes.

The system is currently unavailable. We are working on a solution.

The fault has been rectified.

There is currently a malfunction with the RWTHgpt. A server error occurs after an input.
We are working on a solution to the problem.

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:

https:
www.netzwelt.de/galerie/25894-dns-einstellungen-windows-10-11-aendern.html
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.

Due to hardware upgrades short-term outages may occur.

Due to a technical problem, RWTHgpt is currently not usable. We are working on a solution.

Aufgrund von Erneuerung der SSL Zertifikate wird der vCenter Server im genannten Zeitraum teilweise kurzzeitig nicht erreichbar sein.
Alle VMs laufen wie gewohnt weiter und die Erreichbarkeit der darauf laufenden Dienste wird NICHT durch diese Wartung beeinträchtigt werden. Lediglich die Funktionen des HTML5 Clients für das Management ihrer VMs werden nicht verfügbar sein, da Sie sich während der Wartung nicht am vCenter Server einloggen können.

Während der Wartung ist es zu Fehlern gekommen, sodass die Wartung verlängert werden muss.
