Hello @Sandeep Kumar ,
Apologies for the late response and for the frustration this issue might have caused. Based on the error message, your container is not responding to HTTP pings on port 80. Can you please share with us the docker command you are using so we can see if your Dockerfile is exposed on port 80?
You can use the EXPOSE instruction in your Dockerfile to expose port 80 or
Use the WEBSITES_PORT app setting with a value of "80" to expose that port.
Keep in mind ports other than 80 and 8080 are ignored based on this documentation.
Please let us know if you have further question or if you are still seeing this error
