SNMP Library Sensor SNMPERR_BAD_SENDTO (SNMP error # -12)



I downloaded an MIB file that I converted using the MIB Importer and then copied it to the appropriate directory in PRTG. Everything went smoothly with the MIB importer and there were no errors.

When I attempt to create an SNMP Library sensor with the newly added file, I get the following error: SNMPERR_BAD_SENDTO (SNMP error # -12).

I have an SNMP Receiver setup on my probe device and I show records coming in successfully but I am unable to use this library. Any thoughts on what I may be doing wrong?

This error usually appears if SNMP Requests are sent to the wrong targets. Please check the "Outgoing IP" for monitoring requests in the PRTG Probe Admin if it's correct, and maybe try re-setting it anyway.
