Agent's connection issue.

Hello,

I'm facing a issue with agent based monitoring for both Linux and Windows devices. After failover in HA pool or agent lost connection. It takes couple of hours for agent to re-establish connection. And sometimes they are never coming back. Restart service in this case fails with "Agent restart attempt failed.". There is no issue with agent service on servers as we have checked them. And eventually they will re-establish connection. This is even a bigger problem when it comes to updates or maintenance as after those we see all agents down for a long time.

Any suggestions ? Maybe anyone had the same issue?

As example after today's failovers due to maintenance we had around 1k down agents. And all of them were failing to connect with "Agent restart attempt failed.". After 4 hours we see only 99 down agents. All other agents got re-established on their own.
