Service Announcement - 11 January 2024Change of certificates on the VPN servers

The server certificates of the VPN servers will be switched from the previous Root CA T-TeleSec to the new Root CA USERTrust. No restrictions are to be expected.

If the message "Untrusted VPN Server Blocked!" appears on a client afterwards, please check your certificate stores. Linux users in particular may have to additionally integrate the new root CA with the following command: sudo ln -s /etc/ssl/certs/USERTrust_RSA_Certification_Authority.pem /opt/.cisco/certificates/ca/
