The app is not published for the same processor architecture.Ĭheck the processor architecture in the hosting system and select the correct one during publishment.The web.config contains hostingModel="inprocess" (or it doesn’t).Įither remove it if it is there, or add it if it is not.Execute a publishment and use that web.config. Right click on your project in Visual Studio and go to Publish. The web.config file is missing from the deployment, or the web.config file contents are malformed.Go to IIS, find your Site and click Explore on the write to find the correct path. The app is deployed to the wrong folder on the hosting system.Permissions on the remote machine folders are not set correctly.įor testing only: try adding Everyone and reset permissions on all child objects.Right click on your project in Visual Studio, go to Properties, then Build and correct the Documentation XML file path to relative one. You enabled XML documentation but the XML documentation file path is wrong.appsettings.json or appsettings.json doesn’t contain all necessary settings.Īdd all settings from the correct appsettings file.appsettings.json for the specific environment is not deployed.dotnet version is wrong, run dotnet -version in CMD to verify.dotnet is not installed on the hosting system.Try debugging locally, correct the error and then redeploy. The app did start, but it can’t generate a valid response.That means, after applying a solution, you need to go to the IIS on the hosting system, find the correct application pool, and restart it. Please keep in mind, most solutions require the application pool to restart.

In this blog post I will try to include as many solutions as possible, please feel free to comment and contribute one if it is not included. It comes in many colors and flavors, it is usually a headache because there are multiple reasons why you can get this, it usually includes no (or minimal) information in Application log, and if you are unlucky enough to have two problems that cause this, it is a guaranteed bad day.
