Forge server log [#MOm2Epa] - mclo.gs here is the logs with some issues this server is running all the mods 6 1.16.5
1.16 sponge forge is currently experimental and not recommended for devs let alone public use. Its only really used for testing and then issues raised on the sponge github page.
The issue here is that sponge is trying to access a file that is only on the client (not dedicated server).
