Backburner Server message “A socket operation was attempted to an unreachable network” when submitting network render job from 3ds Max
The message “Error sending on UDP to <IP address>: A socket operation was attempted to an unreachable network” appears on one or more Backburner Server nodes when submitting a network rendering job from 3ds Max.
The Backburner Server program cannot find the Backburner Manager on the local network.
To address this issue , do the following:
Prefer IPv4 over IPv6
Backburner does not work with the IPv6 networking protocol. To fix this, download and run the Microsoft “Prefer IPv4 over IPv6” hotfix on all Manager and Server machines.
Re-enable the Function Discovery Resource Publication networking service
Windows updates may cause the local network to no longer recognize certain PCs. To address this:
- Follow the instructions in the provided link for all machines on the network: PCs no longer recognized in network after Windows 10 version 1803 upgrade
- Reboot the machines and restart the Backburner Manager, Monitor and Server applications on all PCs.
Note: Although the “broadcast servers” error may still appear in some Backburner Server windows after this fix, if the Server app then shows that it has connected successfully to the Backburner Manager, jobs may still render successfully despite this error message.

Reset the Backburner settings on all PCs by following these instructions: Reset Backburner user settings to defaul.
