This error indicates that the desktop client version is too old to communicate with the current core or Edge services. The client receives a response format it does not understand and fails to parse it.

Update the desktop client to the latest stable release: <https://defguard.net/download/>

After updating, retry the connection. No additional configuration changes are needed.
