Host .Net Core Web API on IIS - ISSUE

Host .Net Core Web API on IIS - ISSUE

After uploaded .Net Core web API on IIS server, I faced below issue , but I found solution after some trial and error.

Issue

<div class = "content-container">
 <h3> HTTP Error 502.5 - Process Failure </h3>
</div>
<div class = "content-container">
 <fieldset>
  <h4> Common causes of this issue: </h4>
  <ul>
   <li> The application process failed to start </li>
   <li> The application process started but then stopped </li>
   <li> The application process started but failed to listen on the configured port </li>
  </ul>
 </fieldset>
</div>

Solution

Open web.config file and make some changes as below

Existing Configuration

<aspNetCore processPath="dotnet" arguments=".\CoreApp.dll -argFile IISExeLauncherArgs.txt" forwardWindowsAuthToken="false" startupTimeLimit="3600" requestTimeout="23:00:00" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />

Working Configuration:

<aspNetCore processPath="dotnet" arguments=".\CoreApp.dll -argFile IISExeLauncherArgs.txt" forwardWindowsAuthToken="false" startupTimeLimit="3600" requestTimeout="23:00:00" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />

 1. I had removed ".\" before dll name, as I hosted my application on root folder on server.

2. Removed -argFile IISExeLauncherArgs.txt

I hope that you also resolve your issue by using this solution.

Enjoy !!!
