Cannot connect to the Docker daemon at unix var run docker sock Is the docker daemon running

Question

I've tried every option I could find on the internet, but I still can't get Docker to work.

Scrapy Splash is something I'd want to use on my server.

Here's a list of commands I've used.

docker run -p 8050:8050 scrapinghub/splash
sudo docker run -p 8050:8050 scrapinghub/splash
sudo usermod -aG docker $(whoami)
sudo docker run -p 8050:8050 scrapinghub/splash
newgrp docker
sudo docker run -p 8050:8050 scrapinghub/splash
reboot
sudo docker run -p 8050:8050 scrapinghub/splash
docker run -p 8050:8050 scrapinghub/splash

As you can see, I attempted to restart my server as well, but it was a fail.
