Push fail with "denied: requested access to the resource is denied"

Hello, I’m using Docker Desktop for Windows: I followed the Getting Started tutorial, but I’m not able to push images to my repository. I always get the same error:

docker push marcogrg/getting-started
The push refers to repository [docker.io/marcogrg/getting-started]
36ff03adf20c: Preparing f46df9cf6498: Preparing 0f4c1352b167: Preparing b12c59827877: Preparing 33c549f45c7f: Preparing b745c9620c42: Waiting beee9f30bc1f: Waiting denied: requested access to the resource is denied

I created the repository in Docker Hub, following the instructions in the tutorial, tried both with Public and Private settings, but nothing works. I searched the forum for the issue, but none of the suggested solutions worked for me.

Thanks for your help, Marco
