@Nguyen Duy Anh Tuan 20172888 Thank you for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.

As you mentioned that you have pushed your docker image to webapp and deployed successfully

Post the deployment were you able to see the expected results when you request the root url of web app in the browser?

Are seeing this issue when you are requesting the web app url from the postman? what is the error message your seeing.

If you are running your webapp on free tier app service plan, try scaling out to higher plan and check.

Could you please run WebApp down detector under Diagnose and solve problems of your webapp to understand/identify better and also to see if there were any application code issues.

Try enabling the diagnostic logging and review the log stream logs.

Feel free to reach back to me if you have any further questions on this.

Hi, I appreciate your support. I followed the steps as you instructed and I got this message from "Risk Alert". I used free tier, So is it because I use the free version ?

Thanks

@Nguyen Duy Anh Tuan 20172888 Thanks for your response.
The webapp detector that I have mentioned in my earlier response is this as shown below.

I think those two warnings that you are referring are from Risk alerts not from the webAppDown detector.

You haven't enabled health check on your app service, refer to this documentation to know about health check feature on app service.

It is about that your app is running on single instance and requesting to run on multiple instance by scale-out instance to more than >1 to avoid downtime for your webapp during platform upgrades.
