title: WSL2 Cannot connect to the Docker daemon
body: <p>here is my setup:</p>
  
  <ul>
  <li><code>Windows 10 PRO - build 19041.153</code> - insider program - slow ring</li>
  <li><code>Ubuntu 18.04LTS</code> subsystem in WSL2 mode</li>
  <li><code>Docker for desktop 2.2.0.4</code> - enabled WSL2 integration with my Ubuntu subsystem</li>
  </ul>
  
  <p>I was currently forced to use Windows for development, so I became microsoft insider member and installed ubuntu with WSL2 mode. Docker desktop supports intergration for WSL2, so I tried it... For a week it worked flawlessly. Today after PC restart, I can't get docker running again. Ubuntu can see injected binaries from Docker desktop, but it can't connect to windows hosted docker daemon anymore.</p>
  
  <p>When I call in subsys terminal <code>docker info</code> it returns </p>
  
  <pre><code>$ docker info
  Client:
   Debug Mode: false
  
  Server:
  ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
  errors pretty printing info
  </code></pre>
  
  <p>or with <code>docker-compose up</code></p>
  
  <pre><code>ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?
  
  If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
  </code></pre>
  
  <p>What I've tried already:</p>
  
  <ul>
  <li>expose daemon without TLS with envs like <code>DOCKER_HOST=localhost:2375</code>, <code>DOCKER_HOST=tcp://localhost:2375</code>, <code>DOCKER_HOST=127.0.0.1:2375</code>, <code>DOCKER_HOST=tcp://127.0.0.1:2375</code> => same result</li>
  <li>uninstall Docker desktop and install previous version</li>
  <li>turn off win firewall</li>
  </ul>
  
  <p>I really, really need this to work. Thanks for any ideas. Weirdest thing is it worked yesterday and I didn't make any changes in system from then... </p>
