Have a C8 and C5 linked via Hub Mesh. Been working fine for months. Now it suddenly quit. Both hubs on 2.3.7.145.
I can go in and do a re-connect on both hubs. They connect up. Then about 30 seconds later they drop out. I have re-booted, etc. No help. Nothing in the logs.
What should I try next?
EDIT: OK, now I'm really confused. Both hubs showed devices offline, or not connected. Just for grins I tried one anyway. It worked. And then everything showed up as connected.
