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

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
