We’re running Deadline 10 (version info below) and rendering Unreal 5.5+ through it. We have an on-prem render farm of about 25 machines and are frequently getting the error:
“only one usage of each socket address (protocol/network address/port) is normally permitted”
Deadline install info:
Deadline Monitor 10.3

I’m a 3D Artist, so my Networking knowledge is limited, and I also didn’t install/set up Deadline at the office, but this error is causing quite a headache and a lot of failed renders or slowing us down massively.
I’ve done several netstat commands on machines on port “4433” (assuming this is the default port) to see if there’s anything there causing it, and there’s only ever Deadline exe’s running. Is this what could be causing the issue? (Below is a reference to my workstation’s results)

This has been really frustrating, and I’m not having much luck solving this. Is there something I’m missing? Any help/advice would be greatly appreciated.
Many thanks,
