Hi Sebastian,
We have done collector grouping. So if one collector is not reachable it trying to reach second one. Cause of that agents are showing disconnected but data are coming through those.
Kindly help me on this collector behavior.

Are you sure that ports are open for all collector instances? I think you should open support ticket and post there support archive, it will be faster for you.
