Hello, Is anyone else having any issues with SNMP timeouts on windows servers? I´ve checked the servers to make sure the port is open and it is listening, but whenever I either do the poller or I manually do the snmpwalk I get a timeout. Same thing if I run the snmpwalk from another server. I do get a ping response so I know they can communicate. I have 3 Windows 2012R2 servers that are having this issue, not sure if maybe it was a recent windows update. TIA
Hi Luis,
Did you open the port in the firewall? And did you set your Observium instance as allowed in the Security tab of the SNMP service?

Id usually assume this was firewall related at some point in the path, either on the devices themselves or an intervening firewall thats been tuned to get very jumpy when a lot of UDP gets thrown at a windows system.

I ran a Wireshark capture and got the following. The echo response in the capture says no response found but the observium server and the server in question are pinging fine. There is no network firewall in between these 2 as they are on the same LAN network. Any further advice would be greatly appreciated.
