Hello
after a 99% disk saturation the postgres crashed.
after restarting the postgreSQL and doing some maintenance to the DB via arcgis monitor, everything started working again.
after 5 days I realized that all the agents were disconnected.
I did the following steps.
restarting the agent to see if it would reconnect by itself, instead it doesn't work.
launching the registration command specifying the id --agent-id but nothing it is not possible to reconnect the agent.
it seems similar to my old post, but in that case the agent id command worked

I was trying to view the arcgis monitor client logs, I don't know if it helps, but I noticed this statement
Max consecutive ping failures reached: disconnecting from server

the registration was successful, I had recreated the admin user as viewer instead of admin.
but the mass disconnection anomaly remained
