I am trying to set up a new version of my application on a server but when I try to access to the web site, I get a HTTP error (502.5 - Process Failure).

The service is started and when I check the connection, I don't have any warning. enter image description here

The stdout log :

Expression: [Recursive resource lookup bug]
Description: Infinite recursion during resource lookup within System.Private.CoreLib.  This may be a bug in System.Private.CoreLib, or potentially in certain extensibility points such as assembly resolve events or CultureInfo names.  Resource name: ArgumentNull_Generic

If I try the dotnet cmd to launch the exe :

>dotnet Maquetteur.Web.exe
Failed to load the dll from [C:\temp\MaquetteurWinServer2012_new\hostpolicy.dll], HRESULT: 0x7BF030
An error occurred while loading required library hostpolicy.dll from [C:\temp\MaquetteurWinServer2012_new\]

    <DeleteExistingFiles>False</DeleteExistingFiles>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <RuntimeIdentifier>win8-x64</RuntimeIdentifier>
  </PropertyGroup>
</Project>

I tried different ways to resolve my problem withou success... I can launch it in Debug and Release mode in visual studio.

I think it is a problem with Identity Core because I added it in this new version. Before Identity, I didn't have any problem to set up a new version on my server.

The specs :

Dev
- Visual Studio Community 2017 v15.7.5
- EF Core 2.0.0

Server
- Windows Server 2012 R2
- Runtime .Net Core App 2.0.7

I have maybe missed some information.

Have you an idea why I have this error ?

  • Check server Event viewer, if there's an error, you may find something interesting. Check also here : https://stackoverflow.com/questions/38624453/asp-net-core-1-0-on-iis-error-502-5 – FrqSalah Jul 31 '18 at 14:35
  • Server Event viewer gives me : `Application 'MACHINE/WEBROOT/APPHOST/OPTIMOBEE' with physical root 'C:\temp\MaquetteurWinServer2012_new\' created process with commandline 'C:\temp\MaquetteurWinServer2012_new\Maquetteur.Web.exe ' but failed to listen on the given port '15731'` – Elsassmania Jul 31 '18 at 15:06

I found a solution for my problem.

It was the NLOG dll which causes this problem. I checked what changed between the new version and the other and one of te modifications was the NLOG implementation. I removed it, publish a new version and put it on my server. It worked without errors ! I don't know if the dll is not compatible with my setup or if I used it badly in my program.cs. I will need to do some tests to try to implement this dll again... or just find an other logging dll :)
