scan the docker image error-unable to retrieve auth token

[masabow123]

I tried to scan the docker image with dockle but I got the following error.

2022-07-20T06:30:49.627Z WARN A new version is now available! You have v0.3.10.
2022-07-20T06:31:01.303Z FATAL unable to initialize a image struct: failed to initialize source: unable to retrieve auth token: invalid username/password: unauthorized: authentication required, visit https://aka.ms/acr/authorization for more information.

Referring to the issue(#106) , I upgraded dockle from v0.3.10 to v0.3.11 and tried again, but the following similar error occurred.
(I also tried updating to v0.4.5, but it was the same.)

2022-07-22T04:44:40.677Z INFO Failed to check latest version. not found version patterns
2022-07-22T04:44:52.318Z FATAL unable to initialize a image struct: failed to initialize source: unable to retrieve auth token: invalid username/password: unauthorized: authentication required

This error was sometimes resolved by clearing the docker build cache with the "docker system prune -a" command, but sometimes not, in those cases rebooting the VM resolved it.

The next time it occurs, I would like to solve it by a method other than restarting the VM, so could you tell me the cause and the fundamental countermeasure?

The docker image I used is building from adoptopenjdk/openjdk11:x86_64-ubuntu-jdk-11.0.11_9 with DockerFile.

Thanks
