If your Node dashboard does not display a green plug and says “Not Connected” but your node looks like it is still listening for searches, you have a Zombie Node! Don’t worry, it’s easy to fix, just run the following commands in your nodes terminal window…
$ sudo docker stop presearch-node
$ sudo docker start presearch-node
Then chech that is running with...
$ sudo docker logs -f presearch-node
If that did not work you can try the full node re-installation with the auto-restart option here.
