Connection Lost to Gateway ... Connection Timedout

A bit more information…

Ignition Gateway is v7.2.11
I attached the client diagnostics log for when the error occurs.
It doesn’t log anything in the Gateway Console.
It seems to occur randomly, and never lasts more than a few seconds…
The screen goes gray, and a dialog box appears “Gateway Connection Lost. Connection Timeout.”
Then live again.
All of the clients seem to have the error occasionally, but not necessarilly at the same time.
I ran Wireshark and compared to an older file, but did not see any major traffic differences.

I am running out of ideas. What should I check next?
