System ErrorSNMP::get(): No response from IP

[olegius24]

I am trying to include Cisco 2911 with version 3 snmp in monitoring.
Cacti 1.2.6 (ubuntu 18.04) displays the message - “SNMP system error - SNMP :: get (): No response from 192.168.1.1”.
SNMPWalk on the server processes the request correctly. What could be the problem?

Likely the device isn't respond to SNMP because of a firewall or routing issue or simply doesn't have SNMP.

Check it from the command line using snmpwalk.

Also, if you have SELinux enabled, try putting that into permissive mode to see if works as well because some systems have exec() blocked from apache.

That is not the problem. SNMPWALK is working.
Here is the output of the command:
snmpwalk -v3 -l authPriv -u snmpuserv3 -a SHA -A uuuuuuuuu -x aes -X xxxxxxxx 192.168.1.1:161 | more

Do you have Apache locked down so that it cannot make network connections? There is an SELinux setting and an apache one too I think to prevent outgoing network connections which would block Cacti.
