Can't start addon

[DST73]

Hi,

if I try to start the addon I get the following error

Can't install ghcr.io/cryorig/amd64-netdata-homeassistant-addon:2.2.8: 500 Server Error for http+docker://localhost/v1.44/images/create?tag=2.2.8&fromImage=ghcr.io%2Fcryorig%2Famd64-netdata-homeassistant-addon&platform=linux%2Famd64: Internal Server Error ("Head "https://ghcr.io/v2/cryorig/amd64-netdata-homeassistant-addon/manifests/2.2.8": denied")

Any advice please
