I checked my sd_event.log. The successful ones have SERVER_RESPONSE = OK. This mean you have issue with your sd_event. Checked if HTTP has been enabled on your sd server via the edit server settings. Check if you can telnet to your sd server from the other box on port eg. 30980 that you have set in your sd_event configuration file. Failing all those, install sd_event on your sd server and use that sd_event for checking to confirm whether it's the sd server or the comms to the sd_server. Note: also ensure that your sd_event is at the same sp level as your sd server. Good luck.
