Last night while watching Plex, it just stopped, and now I cannot get docker to properly run at all. Whenever I try to navigate to the docker plugin page on the webui, it throws this error:
Error: "Operation timed out after 30001 milliseconds with 0 bytes received" - Code: 28
Error #0:

When I use the CLI to check the status I get this:

I have no idea how to manage this since I wasn't messing around with anything when this happened. I will note that I had to reinstall OMV last month because the 4.19 kernel would not boot on my machine (it still doesn't, so I'm running 4.14 right now). I also have been getting a python error when running "apt upgrade", and I don't know if that is related.
Where can start to get docker up and running properly, and then where should I look to try and find the root cause?
Thanks
Edit: I just tried stopping the docker process, but it wouldn't quit, so I tried force killing it, and it keeps restarting itself.
