I have an licensed PRTG-Server working in two different networks on the same network interface. I am trying to get informations about an older HP-UPS via SNMP v1.
The device is reachable via PING. The SNMP-community/port on the SNMP-Tester and the Server are completely the same. When I run a test with SNMP Tester I get all Informations I want. When I configure a sensor for this device, the SNMP gets an timeout "-2003".
Even when I try the "Read Device uptime"... SNMP Tester works PRTG Server itself doesnt work
Ping does work, and also other sensors like http e.g.
I can´t find the problem... there is no visible difference. Do you have any idea?
