Move Virtual to new physical server

Help
1

Hi guys, my environment is fully virtualized.
I had to copy the LibreNMS virtual host to a new location for various reasons.
I have reconfigured all IPs, and they seem to be working fine within Libre. I am able to ping all the devices from Libre and from all the devices. I have reconfigured SNMP on all the firewalls and switched to point to the new location. The printers are working fine, but I can not get the firewall and switch updates in Libre. I have tried deleting a switch and adding it again, but I get the following error.
Could not connect to 192.168.0.1, please check the snmp details and snmp reachability
SNMP v2c: No reply with community public

If I fire up the old server, it works fine. is trere a log in libre i can look at.
Thanks

That sounds more like you have firewalling or SNMP config on the devices to only allow connections from the old IP, or different communities.

You can click the 3 dots top right on a device and select Capture to get the debug output of discovery and polling - it will probably only give you that same amount of information. However you could then test the SNMP connection from the command line by adapting the output it gives - that may be quicker and easier for repeated testing.

Thanks,

After a few more gray hairs, it turned out to be that the new SonicOS enables SNMP v3. After two hours on the phone with support, we both learned
of the new setting, LOL.

Thanks
