ASP.NET Core ErrorCode = '0x80004005' : 80008082


I am having difficulty getting an ASP.NET Core 2.2 app running behind IIS 7.5 on Windows Server 2008 R2.

I am able to run the app manually (with dotnet .\WebApp.dll), so I believe the framework/runtime is correctly installed, but there seems to be an issue with the AspNetCore Module when trying to run with IIS. I receive an HTTP 502.5 - Process Failure response from IIS, and in Event Viewer I have found the following error:

Application 'APP_NAME' with physical root 'C:\path\to\app' failed to start process with commandline 'dotnet .\WebApp.dll', ErrorCode = '0x80004005' : 80008082.

I am unable to find information on the error code '0x80004005' : 80008082. Anyone know where I can find the specific meaning of this code?

EDIT: I have seen posts regarding error code '0x80004005' : 80008083, but this does not seem to be the same issue. With that error code, it seems that the app can not be run manually, which I am able to do with no problems.

I now have the app running successfully, and I believe the cause to have been that the app was published as a standalone app instead of framework dependent. I had originally published the app as a self-contained win-x86 app, and neither the default processPath="App.exe" nor processPath="dotnet" arguments=".\WebApplication3.dll" worked.

After publishing as a framework-dependent portable app, things are now working correctly.
