After pushing a new Docker image version, what could be the reason it doesn't appear on Docker Hub?

When an image is pushed to Docker Hub, it is essential to ensure that the correct command is issued to successfully transfer the image. If the correct push command is not executed, the new version of the image will not reach Docker Hub, resulting in its absence on the platform. The command typically looks like docker push <username>/<image>:<tag>, and if there are any mistakes in this syntax or if it is not run at all, the image will remain on the local machine and not be uploaded to Docker Hub.

Other factors may influence the visibility of the image, such as connectivity issues, authentication requirements, or misconceptions about how tagging works, but the primary issue here pertains directly to executing the right command to send the updated image to the repository.
