'IIS 10.0 (Windows Server 2019) For all web pages returns blank page with all feature installed

Good morning. I have seen several topics about the same problem in the forums. But applying the tips equally I can't get it to work for me. I have contracted Windows Server 2019 in the Azure portal, it has IIS 10. I installed all the IIS options, but for any type of content it returns a blank page, even for simple HTML files. I have installed all the IIS options, restart the server, configure the web page with 1 file index.html, but it doesn't work, it only returns a blank page.

What could be left to do?

IIS configuration:

P.S. The default IIS website does not work either.

When my configuration of binding is port 80

I get this in local and in remote

If I change it to the port 8081

I get different bad result

When I test port 80 for my website with Fiddler, I get this error 401

Is the machine's port of the current website occupied by another website/webserver? such as Nginx,Apache.
Besides, I suspect there is something wrong with your network interface since Azure VM has Azure’s networking rules. We have to configure it if we use non-standard ports. Finally, How do you verify if the website works? Have you tested it locally? Please share the website configuration here.
Here is mine.

Then I test it http://localhost:8008/, it works properly.
Feel free to let me know if the problem still exists.

In IIS 8.5, blank page behavior are usually cause by Anonymous authentication enabled and Windows authentication disabled.

Not sure why: No HTTP 500 error page, no error in the event log, not even an URL listed in Chrome debug/network.
