Only time I've seen this is when I have local DNS client issues on the polling server. Like the unbound process stopped, or resolv.conf got borked.

Are you able to reach your devices with their DNS from the server were Observium is running on?

VON: observium observium-bounces@observium.org IM AUFTRAG VON Marios Palechoros via observium GESENDET: Dienstag, 27. Oktober 2020 10:35 AN: observium@observium.org CC: Marios.P@crowe.com.cy BETREFF: [Observium] Many devices shown as down(dns)
Hello all,
I can see in my observium installation that many devices changed their status to down(dns). This is a new installation and we migrated the configuration yesterday on a new server and devices were working properly. At around the same time (14:20:00) a lot of our machines changed their status to down. The message in the Event log is "Device status changed to Down (dns)". I tried to find what the problem may be but I can see SNMP are correct and dns records exist for the systems. Any ideas?
Thank you, Marios
