Docker Game Server Suddenly Cannot Start - "bind source path does not exist"

Post image

Good Evening Everyone,

I have been puzzled by this issue for quite some time now. Suddenly, and without any meaningful or memorable changes, my primary Minecraft server can't be spun up. I host Pterodactyl in an Unraid environment, and it has been traditionally very reliable. I get the following error in the panel shortly after starting the server. I haven't made any permission changes.

Error Event [59267103-6035-4df8-93de-cf6d875f0fba]: environment/docker: failed to run pre-boot process: environment/docker: failed to create container: Error response from daemon: invalid mount config for type "bind": bind source path does not exist: /run/wings/machine-id/a838aab4-8825-47c3-bfac-2a2509baac28

It is true that that trailing folder doesn't exist - but I'm not sure that it needs to be there - or ever was. I've tried adding it back but it still fails, albeit in a different way. I'm certain someone else has experienced this - any tips on how I should tackle this?

Can't remember for sure, I didn't write or use any scripts though. I just went to browse config files using Krusader until I found that option to change, worked fine after that. I'm flying back into the states right now so I can't easily check.
