Last server certificate exchange on 24 July 2024 at 09:10 and next server certificate exchange on 3 July 2025 at 09:10!

The new certificate is used for both standard access (via port 5432) and alternative access (port 5438). Users of third-party P7 communication modules can find all certificates relevant for the exchange at this link. There are also notes here for users who use the Stunnel process in client mode as a TLS wrapper for encrypted Internet connections. Please be sure to read the Readme.txt file included in the archive before making any changes to your installations.

For connection problems with Telekom P7 applications/communication modules:

Please copy the root CA certificates contained in this zip archive to your FileWork or UA-FI installation if they are not available in the corresponding subfolder "/certs".
