ASP.NET application fails to start on Win 10 and IIS 10 - HTTP Error 403.14 - Forbidden

Mojimir Novak

I have an ASP.NET MVC application running on Win 8.1 and IIS Express 7, but Microsoft forced it to change with an update, and now I have Windows 10 and IIS 10.

The application stopped working today (January 4th, 2017, one day).

i end up

service paused

http error 503 service unavailable.

or

HTTP Error 403.14 - Forbidden to configure the web server not to list the contents of this directory.

courtesy

The app's app pool is under a different account. User has privileges on different folders. Logging is enabled.

Question 1

I don't see (important) anything in any logs. It seems that the log is not working properly. I'm not sure, or I can't see them.

Question 2

After starting the application pool, it stops after a few seconds.

In the event log I only have this:

event log

  1. Error: Application pool 'MyApp' was automatically disabled due to a series of failures in servicing this application pool. --

  2. Warning: The listener channel for protocol 'http' in worker process '8924' serving application pool 'MyApp' reported a listener channel failure. The data field contains the error number. 5139-

Notice

When I run this application on a different computer than Visual Studio, it is working.

question

  1. Why don't I see any errors in the logs? Where are you still looking?
  2. Where to start looking for problems?

After resolving this error in IIS 10, I managed to convert from HTTP Error 503 to HTTP Error 403.14. For this case, the solution is to add

<system.webServer>
   <modules runAllManagedModulesForAllRequests="true"/> 
</system.webServer>

into the project Web.configfile.
