unable to find valid certification path to requested target

[Berlin53]

Some backgrounds from the Berlin Geoportal can no longer be loaded. The cause appears to be a new certificate for the website gdi.berlin.de dated July 30, 2026, which has not yet been added to the system.

Please add the Telekom root certificate ‘Telekom_Security_TLS_RSA_Root_2023.cer’ to the certificate store. Tested successfully!
