Hi @Shubham Sanap ,

Thank you for reaching us regarding the issue that you can’t pull your container image because it’s hitting a 401/403 (“unauthorized” or “forbidden”).

Could you please confirm which service you are using, such as App Service or Container App?

We are using the Azure Web App Service. Can we schedule a call to check how this incident happened ? There have been no configuration changes, and there are no expired certificates.
