Hi Tobias.
The "send command" is set to null once the clip list fetch has been started. The fact that it is constantly connecting/disconnecting without any messages coming in has me suspecting that there is an issue with the port on the Hyperdeck side. To be sure, you may want to wrap the listener code in a try { .... } catch (e) { ogscript.debug('EXCEPTION: ' + e); } to see if there is another hidden error that is being missed.
The other commands (play/stop/cue) establish a separate connection to the Hyperdeck side - if these are also failing it would again point to an issue opening a connection on that port.
Overall, I would recommend checking your Hyperdeck settings to make sure it is still listening on your configured port and accepting commands with that API. In a pinch, you could try using a program like Putty to directly-enter the desired commands to the Hyperdeck to verify that other applications are still able to connect/communicate over that port/API.
