Information:
On macOS operating systems with version 15.2 (Sequoia), the “Connect” button is grayed out in the LANCOM Advanced VPN Client version 4.70 REL. As a result, no VPN connection can be established with the client.
There is currently no solution for this behavior.
A software version that fixes the behavior is in the works and will be released shortly (probably calendar week 51/2024).
