Trouble installing the flicd service

[graywizardx]

I am sure this is probably on my end but I am getting this in the log and not exactly sure how to troubleshoot it:
21-12-03 17:33:21 ERROR (SyncWorker_4) [supervisor.docker.interface] Can't install pschmitt/home-assistant-addon-aarch64-flicd:2.0.3: 500 Server Error for http+docker://localhost/v1.41/images/create?tag=2.0.3&fromImage=pschmitt%2Fhome-assistant-addon-aarch64-flicd: Internal Server Error ("Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io: no such host")

I cannot find anywhere in the code or the local container that it is using registry-1 and so not sure where to look next.

Any help would be appreciated,

You're lacking internet connectivity, or your DNS server is not working. Either case, not a flicd addon issue.
