Receiving recurring alerts on most of my devices that SNMP is not responding on Device. Discovery and polling work correctly. Checking on device not polled lists 0 devices. This is a fresh / brand new install of LibreNMS on a fresh / brand new install of Ubuntu 22.04.4 LTS.

./validate.php shows everything is good also.
./validate.php

Update:

I thought it was most of my devices, however I was wrong. Looking at my e-mails there are 8 devices that are constantly alerting out of the 35 devices I am currently monitoring. 5 of those devices are Windows Servers. 1 is an ASA running ASA code, 1 is an ASA running FTD code, and 1 is FMC managing the ASA running FTD code.

I had an older install of LibreNMS that this fresh install replaced. The older version did not have these false positives. Again, TIA for any help!

This can be safely closed. The alerts were coming from the old server which I thought was powered off, but was not.
