I’m working on windows with a 4.7.6 build - I have built from source however nothing has been modified.

When I try to run the server with my map as the default (as set in the editor) - it crashes immediately with this message:

I’ve built the server using :

Does anyone know what I’m doing wrong?

Ok, I had the same issue and managed to fix it. I think the error is because I was running the server executable from the wrong directory. I had to copy it to my packaged directory and run it from there, ie:

\WindowsNoEditor\SpaceCoop\Binaries\Win64

Doing that resolved the error and the map loaded correctly. If you are having trouble getting a dedicated server working, this tutorial is GOLD:
