[0.16.16] Linux Headless not working despite appearing to

[huntinator7]

I'm running a headless 0.16.16 server on an Ubuntu linux server, and it appears for all intents and purposes to be running correctly. I have it installed to /opt/factorio, used a port I know is working with other games, configured the server-settings with my username and token (also tried with password), moved a world zip into a saves folder in the root, and the command line looks like it's working.

Code: Select all

sudo /opt/factorio/bin/x64/factorio /opt/factorio/data/server-settings.json --start-server-load-latest

But when trying to connect directly on the same version, it shows the "Couldn't establish network communication" notice, and the server does not appear on the server list. Is there a step I missed, or does the output show anything that is going wrong? I can provide the server-settings.json or more detailed instructions of what I did if that would help. Thanks

The interesting part would come right after your log ends, so either the server is just misconfigured, it froze or the rest of the log just got lost. Post your server settings file please, make sure to mask any passwords.

That's what it shows when I ctrl-C, no logs when anyone tries to connect. Server settings here https://drive.google.com/open?id=1feain ... Oia-S8-Y91

Try replacing

Code: Select all

/opt/factorio/data/server-settings.json

with

Code: Select all

--server-settings /opt/factorio/data/server-settings.json

That worked! Thank you so much for the assistance.
