I am working on building a remote event receiver for our SharePoint online root team site. and i am following the main approach mentioned in this link remote-event-receivers-youre-all-doing-it-wrong. where the approch worked well when i debug it using ngrok and running it from VS 2019. but when i deploy the RER inside azure web app, the RER stop working. Here are the details for the problem:-
1- Inside VS 2019 >> create a new asp.net web application >> add a .svc named rer.svc.
2- I generate the client and secret id, using this url https://****.admin.sharepoint.com/_layouts/15/appregnew.aspx
3- Then i access the app from the SP admin center @ https://***-admin.sharepoint.com/_layouts/15/appinv.aspx + i add this permission:-
<AppPermissionRequests AllowAppOnlyPolicy="true">
<AppPermissionRequest Scope="http://sharepoint/content/tenant" Right="FullControl" />
</AppPermissionRequests>
4- I updated the asp.net web.config file with the client ID + secret ID generated from step-2.
5- I create a new App service inside azure with this url https://tgrouppusrer.azurewebsites.net/rer.svc.
6- After that i deploy the asp.net web application into azure using ftp :-
7- I access the service https://tgrouppusrer.azurewebsites.net/rer.svc, and i got this page:-
8- Finally i register 2 remote event receivers using this PnP script:-
Add-PnPEventReceiver -List "Project System" -Name "PUSRERupdating" -Url https://tgrouppusrer.azurewebsites.net/rer.svc -EventReceiverType ItemUpdating -Synchronization Synchronous
Add-PnPEventReceiver -List "Project System" -Name "PUSRERupdated" -Url https://tgrouppusrer.azurewebsites.net/rer.svc -EventReceiverType ItemUpdated -Synchronization Asynchronous
so on paper i should have everything working well. but when update a list item inside our "Project System" list, the RER did not have any effect. so i open the azure application server logs and once i update a list item the logs will show this error:-
The default timeout is 2 hours. Change the timeout with the App Setting SCM_LOGSTREAM_TIMEOUT (in seconds).<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><title>IIS Detailed Error - 404.0 - Not Found</title><style type="text/css"><!--body{margin:0;font-size:.7em;font-family:Verdana,Arial,Helvetica,sans-serif;}code{margin:0;color:#006600;font-size:1.1em;font-weight:bold;}.config_source code{font-size:.8em;color:#000000;}pre{margin:0;font-size:1.4em;word-wrap:break-word;}ul,ol{margin:10px 0 10px 5px;}ul.first,ol.first{margin-}fieldset{padding:0 15px 10px 15px;word-break:break-all;}.summary-container fieldset{padding-bottom:5px;margin-}legend.no-expand-all{padding:2px 15px 4px 10px;margin:0 0 0 -12px;}legend{color:#333333;;margin:4px 0 8px -12px;_margin-font-weight:bold;font-size:1em;}a:link,a:visited{color:#007EFF;font-weight:bold;}a:hover{text-decoration:none;}h1{font-size:2.4em;margin:0;color:#FFF;}h2{font-size:1.7em;margin:0;color:#CC0000;}h3{font-size:1.4em;margin:10px 0 0 0;color:#CC0000;}h4{font-size:1.2em;margin:10px 0 5px 0;}#header{width:96%;margin:0 0 0 0;padding:6px 2% 6px 2%;font-family:"trebuchet MS",Verdana,sans-serif;color:#FFF;background-color:#5C87B2;}#content{margin:0 0 0 2%;;}.summary-container,.content-container{background:#FFF;width:96%;margin-padding:10px;;}.content-container p{margin:0 0 10px 0;}#details-left{width:35%;float:left;margin-right:2%;}#details-right{width:63%;float:left;}#server_version{width:96%;_height:1px;min-height:1px;margin:0 0 5px 0;padding:11px 2% 8px 2%;color:#FFFFFF;background-color:#5A7FA5;border-bottom:1px solid #C1CFDD;border-font-weight:normal;font-size:1em;color:#FFF;text-align:right;}#server_version p{margin:5px 0;}table{margin:4px 0 4px 0;width:100%;border:none;}td,th{vertical-align:top;padding:3px 0;text-align:left;font-weight:normal;border:none;}th{width:30%;text-align:right;padding-right:2%;font-weight:bold;}thead th{background-color:#ebebeb;width:25%;}#details-right th{width:20%;}table tr.alt td,table tr.alt th{}.highlight-code{color:#CC0000;font-weight:bold;font-style:italic;}.clear{clear:both;}.preferred{padding:0 5px 2px 5px;font-weight:normal;background:#006633;color:#FFF;font-size:.8em;}--></style>

Generally speaking why it is trying to connect to "https://tgrouppusrer:80/rer.svc" while it should connect to "https://tgrouppusrer.azurewebsites.net/rer.svc" as specified in the PnP script to add the RER? could this be the problem?
Here is a screen shot of the above error when i save it a html:-
also inside Kudu i can see that the rer.srv is there, as follow:-
Also my original web.config is as follow:-
