I don't know how to check for the OpenGL backend on the server. Neither
do I know if that would effect the "export scene" feature.
Where is the rendering done, server-side or client-side?

If you know that your client is compiled with the old OpenGL backend,
you could enforce the rendering on the client and see if that works. To
do that you have to adjust the remote rendering threshold in the settings.
