Installation of Storj on RaspberryPi 4

Error: invalid contact.external-address: lookup “.ddns.net” failed: lookup .ddns.net on 180.151.151.151:53: no such host.

This error shows up when running the following command:
$ sudo docker logs --tail 20 storagenode.

please help how to rectify this error.
please help how to install storj and create storage nodes on rpi4

This is not a full DNS name, you need to fill the ADDRESS field with your full DNS name (e.g. mynode.ddns.net, but the real one) in the docker run command.

To be able to help you need to give alot more information. What does your docker start up command look like?
