I'm running a remote probe locally on a device that I want to monitor using SNMP. Everytime I try to add a sensor I get the error "SNMPERR_BAD_SENDTO (SNMP error # -12)". What can I do to make it work?

localhost snmp snmp-error-#--12 snmperr-bad-sendto

Please try to add a new device that is using the "external ip address" of the device. We've encountered some problems that could be fixed by avoiding "localhost", "127.0.0.1" and "::1" with SNMP.

I have an identical problem, but using the "external" IP address has not corrected the issue for me. Is there anything else I could try please?

Hello,

Does your device use multiple NICs? If so, please try to use another address. Furthermore you can use the SNMP Tester and scan the device for e.g. the uptime. Which result do you get using the tester?

Best regards
