HTTP Error 503. The service is unavailable in IIS?

I published my Web Api (framework 4.5) in this path C:\inetpub\wwwroot\MyWebAPI

In my IIS i converted this folder to an app

When i try to access this URL http://localhost/MyWebAPI/api/client/1 a message appears

Service Unavailable

HTTP Error 503. The service is unavailable.


My App Pool is set to be "STOP", i turn it on but it goes back to "STOP"

I found the solution

  • Click on Application Pools under the tree with your machine name,
  • on the right side, click click on Advanced Settings,
  • in Process Model change the "Load User Profile" to false
  • Start your apllication and restart your IIS

The error will surelly change, in my case the error changed to this one

"Config Error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false"."

I have found the solution for this other problem here IIS - this configuration section cannot be used at this path (configuration locking?)
