False Positive Monitored Nodes Maintaining 100% Packet Loss

My team has been experiencing a significant number of false positive over the course of the past month.This only happens with nodes that are being polled with the SolarWinds Agent. When clicking into the edit properties page of the node, it will show that the Agent software is installed and shows in green that it is functioning properly however it is not. We have tried restarting the Agent Service from the manage Agents page but that does not work. The only workaround that we have found is to switch the nodes to ICMP, rediscover, poll now and to then switch it back to Agent. So on any given day we can have around 100 nodes that have to manually be corrected, which takes up a large chunk of time. We have opened a ticket with the SolarWinds Customer Portal, however we aren't getting much help, our logs report no issue. The service account the we are using for the Agent is not an issue, we are on the current version for the Agent as well. Please assist with any advice.

Similar problem I would fix by setting the node to "unmanaged" for a couple minutes then re-manage. Note, it had to be unmanaged and not muted. It was ok to do a schedule unmanaged, so you don't forget to re-manage it. I never found a fix, but my issues seemed to go away when I upgraded to 2022.4.1.

@brscott No luck with using the 'unmanaged' function. Tried it for a few minutes and it didn't effect the packet loss. Then tried for a period of 30 minutes and still no difference. Checked the capacity of the MPE and its no where near capacity, the additional polling engines arent either & the issue happens on all of them.

1) Contact your sales person, see if they have any insights into why this is taking so long to get resolved. If you don't have or don't know your sales person, you can summon one with an easy spell on the website called "request a quote".

2) Are the agents "Agent Initiated" or "Server initiated"? Can you switch them to the other method? Switching is not a solution, since either should work, but it can help narrow down the issue. Unfortunately, I don't know how to switch it, without deleting the agent from orion, and uninstalling from the node. Then re-installing.
