Cannot pull image from private registry, got error `error pulling image configuration: unknown blob`

I have hosted a registry with docker image.
I could push image to it, but when I try to pull image. I got the error below:

error pulling image configuration: unknown blob

Could someone help me fix this?

I had the same on Windows when host OS was incompatible with container OS.
You didn’t specify your environment, but if it’s Windows, check this Compatibility matrix: https://docs.microsoft.com/en-us/virtualization/windowscontainers/deploy-containers/version-compatibility

https://docs.docker.com/v17.09/registry/insecure/#use-self-signed-certificates

not sure if you are using self-sign cert. you will need to add cert to all nodes in order to have node access local registry via ssl
