Getting an error "You do not have permission to view this directory or page." when trying to browse deployed application using Azure App Service?

Question

I am trying to browse a deployed application using Azure App Service. A build and release pipeline was used to deploy the application. I do use an active service connection that connects to my subscription, which includes the Azure App service I am using. I did check that the pipelines I am using are allowed to use the service connection. They were existent in the usage history of the service connection. I also already checked that the deployment was successful from the Azure DevOps side and uses the correct app service.

I also have some attached screenshots with some permissions currently established for myself regarding the app service, subscription, etc.

Can you please give me an idea of what the root cause might be in this case?s.png]4

Answer 1

For anyone facing the same issue deploying ASP.NET core to app service through azure pipelines, you may check to see if web.config will is in the build files else you can add the web.config file. I had the same issue and in my case, adding the web.config fixed it for me.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="dotnet" arguments=".\YourAspNetCoreApp.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
  </system.webServer>
</configuration>

@Evan Sanford , thank you for reaching out to us. A usual cause for this type of error after deploying through pipelines is a miss in the pipeline. To find more information about the miss, can you enable detailed Logging in the App Service by following Hafiz's answer here: Azure website message “You do not have permission to view this directory or page.”. What to do??. After this, you will get to know about the exact miss in the deployment.
