At the beginning of August, I set up QNAP NAS probes on my distant sites, everything worked correctly.
However, for 1 month I have losses of connection of probes saying to me "No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (erreur SNMP # -2003)", it is rather annoying.
But when I make "10000" updatings, sometimes that becomes in green. When I introduce a connection on the NAS (Web panel), the probe becomes directly in green.
Would you have a solution to this problem?
For your information, my PRTG is always up to date.
