It means I could the OpricsRE generated error notification that we went offline followed sometime later by notication of being back on line, repeated another 3 interations except lack of back online notication.
This is not something new other than I didn't used to have notification turned on. This happens randomly, no set interval as to going offline, no set recovery period.
Most of the time I can get the offline notification, trudge out to the system, pull the Mate3 and it resets. I do this because I really don't like the data check up if it stays off line too long and I get a hole in the graph followed by a spike.
So hoping for clarity, the initial 3 1/2 were the 7 email notifications, the last 4 were me standing at the Mate 3, pulling plug, checking on iPad OpticsRE site, then giving up after 4th try. And double checking I had a good internet connection. First notification was 12:03 midnight, last 2:03
I'd say this issue has been brought up numerous times over the past year, just described differently.
