So my Mattermost container just stopped working an hour or so ago for some reason. I haven't changed the configuration at all I just suddenly noticed that the container stopped and now I can't start it again. In the log it is giving this error: "failed to load configuration: failed to create store: unable to load on store creation: failed to persist: failed to write file: open /mattermost/config/config.json: permission denied"
I haven't changed any permission settings between when it was last working and now so I'm not sure what happened. Any help would be appreciated!
