The error message "Status: 401 Unauthorized" indicates that the authentication credentials used to access the Azure Container Registry are incorrect or invalid. This error can occur due to various reasons such as incorrect username or password, expired access token, or incorrect registry name.

To troubleshoot this issue, I would recommend you to follow the below steps:

Verify if the username and password used to access the Azure Container Registry are correct. You can use the docker login command to authenticate with the registry and verify if the authentication is successful.

Check if the access token used to access the Azure Container Registry has expired. You can generate a new access token and try accessing the registry again.

Ensure that the registry name used in the Azure Pipelines is correct and matches the name of the Azure Container Registry.

Verify if the Azure Pipelines are configured correctly to push the images to the Azure Container Registry. Ensure that the pipeline is using the correct registry name, username, and password.

Check if there are any firewall or network security group rules that might be blocking the communication between the Azure Pipelines and the Azure Container Registry.

If you have already tried the above steps and still facing the issue, I would recommend you to contact Microsoft Azure Support for further assistance. They will be able to provide you with more specific troubleshooting steps based on your environment and configuration.

Regarding the issue of images not reflecting in the Azure Container Registry, it could be due to various reasons such as incorrect registry name, incorrect image tag, or network connectivity issues. I would recommend you to follow the above steps to troubleshoot the authentication issue first and then verify if the images are being pushed to the correct registry and with the correct image tag.

I hope this helps you to resolve the issue.

Found a solution to this. Basically, you need to add the permissions to yourself.

1: Go to the container registry.

2: Select Access Control(IAM).

3: Click on "Add role assignment" under "Grant access to this resouce"

4: Now go to "Priiledged administrator roles" and select "Owner"

5: Click on "Next" at the bottom of the page.

6: Now click on "Select Members"

7: Add yourself (via email or name) and click on "Select" at the bottom of the right expanded pane.

8: Click on "Review and Assign"

This should fix your issue.
