I keep getting this error. I have no mods. It happens whether I create the file on the server or create the file on my client. I have no mods. I have reinstalled all files. I have created a file with no changes to generation. I have made no changes to server-settings.json. "multiplayer" is the name of the save file.

You need to give path to the save and the file suffix, see https://wiki.factorio.com/Multiplayer.

like this? Program arguments: "/opt/factorio/bin/x64/factorio" "--start-server" "/opt/factorio/mods/mp.zip"
Same result

Why do you put the save into the directory for the mods?

The game scans and attempts to parse all zips in the mods directory. So, please, don't put random stuff there.

To fix your problem: remove everything that is not the mod from the mods directory, put save into the saves directory.

Oh my. Honestly, I don't know why I put it in there. I obviously did but I don't recall doing it. Thank you!
