Section control, Machine board intermittently loses connection on UDP

I am using version 6.2 of AgOpenGPS with Xilofeon (Daniel Desmartins) section control over UDP. I have 5 switches so changed from 7 to 5 in the sketch and changed UDP to true. I think I have it configured correctly, it connects with AIO and I can use if for awhile on the simulator and everything is fine then for some reason AIO loses connection with it. If it loses connection for long enough the relays drop out but it continues to paint. I tried it in the field and the same thing happens. I have changed cables, changed the USR serial to Ethernet board. It will work on simulator for 15 or 20 minutes and then go thru a stretch of losing connection on and off for awhile. Any ideas on what to check or change. Thanks for looking.

I have same behavior. But connection stays working. It is anoying agio every time opens in screen. So I will follow this.
