I am having an issue with my UDP connection. When I first set it up, the driver initially showed that it was not using Multicast, but when it wouldn’t connect, I found that Multicast was checked. I unchecked Multicast, and the system started working. It worked fine for a day or two, then stopped. When I went back into the device, Multicast was checked again. I unchecked it, and now the device is working properly. What could be causing the Multicast bit to be set? I am running 7.8.2 with java 1.8.77
