Webex Client cannot connect to the telephone system
We have determined that not all of the certificates required for our new certification authority “HARICA” are available in some Windows operating systems.
If the “HARICA TLS RSA Root CA 2021” certificate is missing on your computer, services that operate with HARICA certificates will no longer function here. This affects telephony (softphone, Webex), for example.
To fix the problem, the “HARICA TLS RSA Root CA 2021” certificate must be installed on the affected computers.
The official certificate can be downloaded from the manufacturer at the following link:

repo.harica.gr/certs/HARICA-TLS-Root-2021-RSA.der
Login not possible
RWTH Single Sign-On login ist not possible at the moment.
Existing sessions are not affected.
We are working on fixing the problem.
Login via RWTH Single Sign-On not working
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.
Routing über neue XWiN-Router
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.
Umsetzung des Lifecycle Managements
Im Rahmen der Implementierung des Lifecycle Managements deaktivieren wir heute Accounts, die nach uns vorliegenden Angaben keine Gültigkeit mehr haben sollten.
Sollte ihr Account unberechtigt deaktiviert worden sein, melden Sie sich bitte beim ServiceDesk.
Kurze SSO-Störung
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.
Short Failure of the Uplink to Frankfurt
Due to a brief disruption, there are various network and telephony failures at the RWTH. The reason for this is a fibre break in an uplink to Frankfurt.
Single sign-on and MFA mailfunction
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.
Hohe Latenzen zentrale RWTH Firewall
Aufgrund hoher Last auf der zentralen RWTH Firewall kam es zu erhöhten Latenzen, wodurch insbesondere Videokonferenzen gestört wurden. Durch die Deaktivierung ein paar nicht essenzieller Dienste konnte das Problem behoben werden. In Kürze ist eine Leistungssteigerung der Firewall geplant, um zukünftig genügend freie Ressourcen zu schaffen.
Short problems while using RWTH Single Sign-On
For a short period of time, there was an error while using RWTH Single Sign-On.
The problem has been solved.
Expired certificate
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.
Lizenzwechsel
am 21.9.2024 startet unser neuer Wartungsvertrag im neuen Lizenzmodell von Cisco Webex. Wir vertrauen darauf, daß Cisco den Lizenzwechsel ausfallfrei absolviert.
Wartung des Datenbankservers
Wegen einer Wartung des zugrundeliegenden Datenbankservers ist im Wartungszeitraum mit Ausfällen von Webdiensten zu rechnen:
* NOC-Portal (z.B. DNS-Admin, DHCP-Admin, RADIUS-Admin, Interface-Admin, WLAN Gäste einrichten)
* TK-Portal
* RA-Portal
Die Dienste laufen wie gewohnt weiter. Bitte versuchen Sie zu einem späteren Zeitpunkt Ihre gewünschten Änderungen einzutragen.
Multifactor-Authentication for the RWTH Single Sign-On
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].

Login via RWTH Single Sign-On Partially Not Possible
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.
Webex-Account kann nicht aktiviert werden
Aktuell kommt es bei einzelnen Personen, die noch keinen Zugang zur Cisco Telefonanlage haben, beim Zugriff auf das TK-Portal zu einer Fehlermeldung.
Wir arbeiten an einer schnellstmöglichen Lösung des Problems.
Ansetzen von Webex Meetings gestört
Bei dem Versuch, sowohl über den client als auch über den Browser, ein Webex Meeting anzusatzen lädt das aufkommende fenster sehr lange bevor teilweise eine Errormeldung erscheint.
Netzwerkstörung
Currently, external websites cannot be accessed. We are working on a solution.
Telephony may also be affected.
