Deploy ASP.NET core web app which used Azure AD authentication on linux server - asp.net-core

Question

When I deploy my asp.net core web app which used Azure AD authentication on a Linux server, it runs using an IP address with a particular port number using HTTP protocol. Azure portal does not allow HTTP protocol with IP address. It has to be HTTPS. How can I run my application with HTTP protocol which is using Azure AD authentication?
I tried to add the new IP address on azure ad portal but it does not allow IP addresses with HTTP protocol(only localhost is allowed for HTTP). If I add HTTPS then I am getting error
The redirect URI 'url' specified in the request does not match the redirect URIs configured for the application ''
I tried to add full path for "CallbackPath" in the appsettings.json file. When I run the application, I get error of
ArgumentException: The path in 'value' must start with '/'. (Parameter 'value')
I want to run my applciation on a linux using ip address with HTTP protocol. How can I solve this problem?

I Tried to reproduce the same in my environment to deploy .Net Web Application on Linux Server:
I created a linux virtual machine, like below.
Azure Portal > Virtual machines > Create > Create a virtual machine.
Connected to Linux VM Using Putty.
Install .Net Core on Linux Server by using below commands, See the :MS document here
wget https://packages.microsoft.com/config/ubuntu/22.10/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
rm packages-microsoft-prod.deb
Install required libraries and .Net SDK using below cmds.
sudo apt-get update && \
sudo apt-get install -y dotnet-sdk-7.0
sudo apt-get update && \ sudo apt-get install -y aspnetcore-runtime-7.0
sudo apt-get install -y dotnet-runtime-7.0
Transfer the .Net web application to linux server using winSCP, follow the document here
Once copy the files to linux server, navigate to root folder (publish folder) and run run dll.
dotnet linuxapp.dll
once ran the .dll files, test the web application using below cmd.
curl http://localhost:5000
To check the web application on public IP, we need to install Njnix, follow the document here
sudo apt update
sudo apt install nginx
once install the nginx, test the web application using public IP.
If the nginx application is running, stop the ngnix service using below cmd.
Configre nginx -stop the nginx service
sudo service nginx stop
Go to root folder= etc= nginx= sites- available = default (check the permission) by using WinSCP and update the location with below values.
location / {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
Once update the files, then start the nginx service using below cmd.
sudo service nginx start
Note: Make sure add HTTP Inbound role on VM, like below
Run the dotnet linuxapp.dll again
dotnet linuxapp.dll
Once ran the dll ,test the web application with public IP.

When we create the App Services service, it will automatically assign the certificate and then we have to use HTTPS.
But we can access our Azure app service via http by adding a custom domain name without binding a certificate.
And for this error messgae:
The redirect URI 'url' specified in the request does not match the redirect URIs configured for the application ''
We should check the App registrations in azure portal, not appsettings.json.
