I am a student with 2 others in my project. we connected 3 RPi sending temp and pressure to my Project channel using fields 1,2 3,4, and 5,6 we were publishing the data from 3 python scripts i wrote and everything was working great and the charts were update then it just stopped publishing. I thought it might be a license/message problem as i was sending information every 1 sec so I changed it to ever 60 sec. Everything worked fine again for 5 minutes and then it all crashed It will not let me reconnect and i can't see any data updating from the other Rpi's any Do you have a technical help line or how should i proceed.
