title: Docker swarm - Manager node cannot access the containers in worker node
body: <p>In our docker swarm environment, there is 1 manager nodes and 2 worker nodes.
  We also installed portainer,swarm and the portainer agent's &amp;swarm agents on all nodes.</p>
  
  <p>Yesterday, one of the virtual servers which worker node installed rebooted unexpectedly.
  When we check the docker service it was stopped. restarted the docker service with using this command:</p>
  
  <pre><code>systemctl restart docker
  </code></pre>
  
  <p>Then all the containers seem to work fine on the worker node. But when we check the containers by the portainer which runs on a master node, the containers look stopped. Swarmpit reports that the worker's nodes active and ready.
  What could be the problem?</p>
