Pulling docker image, unauthorized: authentication required

Question

Hello, in general, I can't make a Container Web App download the image from Azure Container Registry. There next error in the logs:

2023-10-23T21:58:20.132Z ERROR - Pulling docker image release.azurecr.io/dqs/dqsicmservice:release failed:
2023-10-23T21:58:20.240Z ERROR - DockerApiException: Docker API responded with status code=InternalServerError, response={"message":"Head \"https://release.azurecr.io/v2/dqs/dqsicmservice/manifests/release\": unauthorized: authentication required, visit https://aka.ms/acr/authorization for more information."}
2023-10-23T21:58:20.240Z WARN  - Image pull failed. Defaulting to local copy if present.
2023-10-23T21:58:20.242Z ERROR - Image pull failed: Verify docker image configuration and credentials (if using private repository)

For this Web App Identity is enabled and Role AcrPull is assigned but docker still can't download the image. What is missing here?
