Installation of HA on RP4 hang up - ghcr.io will not install

I’ve changed DNS, rebooted router, relashed SD, obtained new SD but getting hung up. HA Observer shows unhealthy - Supervisor. Tried to update supervisor with CLI and get same error message as in logs:

Error: Update of Supervisor failed: Can’t Install ghcr.io/home-assistant/aarch64-hassio-supervisor:2023.12.0: 500 Server Error for http+docker://localhost/v1.43/images/create?tag=2023.120&fromImage=ghcr.io%/Fhomeassistant%Faarch64-hassio
-supervisor&platform=linux%2Farm64 Internal Server Error (“Get “https://ghcr,io/v2/”: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)”)

I’m am a newbee with HA and Linux, but please try to help if you can

I solved this problem by setting my Netgear router to Dynamic DNS.
