I'm trying to deploy FastAPI app on IIS.
I followed this guide from Microsoft.
My web.config looks like
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="PythonHandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified"/>
</handlers>
<httpPlatform processPath="c:\Python\Python310\python.exe"
arguments="uvicorn main:app"
stdoutLogEnabled="true"
startupTimeLimit="60"
processesPerApplication="16">
<environmentVariables>
<environmentVariable name="TEMPLATE_STRING" value="some-random-string-text" />
</environmentVariables>
</httpPlatform>
</system.webServer>
</configuration>
When I'm trying to browse the application, I'm getting an error
HTTP Error 502.3 - Bad Gateway
There was a connection error while trying to route the request.
Most likely causes:
1. The CGI application did not return a valid set of HTTP errors.
2. A server acting as a proxy or gateway was unable to process the request due to an error in a parent gateway.
Can someone point out to me in correct direction. It's my first time working with Windows Server (2019) and IIS (10).

Could you please solve the issue
I'm trying to deploy a netcore2.0 MVC app to IIS and keep getting the error above.
The file permissions are set correctly and I checked that the runtime is downloaded.
The error is as follows:

This error occurs because the ApplicationHost.config or Web.config file contains a malformed XML element, you need to delete the malformed XML element from the ApplicationHost.config or Web.config file.
You can also refer to this link about how to deploy ASP.NET Core on IIS: Host ASP.NET Core on Windows with IIS.
I'm trying to host two applications in IIS in Windows Server 2019, in the same site. One of the applications is a website's front-end, in Angular, and the other one is the website's API, in ASP.NET MVC (.NET Core 2.2.8).
The front-end application's URL is site_url/portal and the API's is site_url/api.
Before using the API's other actions, one has to request a JSON web token from the site_url/api/identity URL, using Windows Authentication.
The front-end seems to be working fine, but trying to reach the site_url/api/identity API in the quality control environment yields "HTTP Error 500.0 - Internal Server Error".
I activated detailed logs in IIS and the error message in Event Viewer was "Could not load configuration. Exception message: Attribute 'processPath' is required."
The API's web.config file does have a process path:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\PortalAPI.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" forwardWindowsAuthToken="true"/>
</system.webServer>
</location>
</configuration>
Aditionally, the IIS error page shows something which I find strange. The request URL is correct, but the physical path is application_path\identity. "Identity" is an MVC controller, not a file.
The .NET Core 2.2 Windows Hosting Bundle is installed and the .NET path environment variable is set.
The application pool identity is an applicational user, and .NET CLR version is set to "No Managed Code".
The site has both Anonymous Authentication (for the front-end login page) and Windows Authentication enabled.
The thing is, I have hosted the applications in the exact same way in both the development environment and a clean Azure virtual machine, and they work in both, which makes me think this has to do with some setting in either IIS or the quality control machine itself.
Does anyone have any idea what the problem and/or possible solutions might be?
A missing configuration caused this error for me until I added it: environment variable ASPNETCORE_ENVIRONMENT
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\PortalAPI.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" >
<environmentVariables>
<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Development" />
</environmentVariables>
</aspNetCore>
</system.webServer>
You can put this in web.config, but it will get removed if you publish a new version of the web app from Visual Studio. To avoid that, put it in applicationHost.config instead (in the location corresponding to your site).
We are moving our websites from a 2008 r2 server running IIS 7.5. The first program I moved over was asp.net core when attempting to run it I get the error HTTP Error 500.19 - Internal Server Error with the error code 0x8007000d. This starts my internet search unfortunately I don't have a config error which would narrow down the search quite a bit and none of the solutions I found worked. This code works on the old server just fine and I don't have anything in my code specifying the cpu so it not set to 32 bit.
Everything I have tried points me in the direction that the web.config file cannot be accessed. one of the reasons I say that is when I try to open configuration editor I receive the error the data is invalid (Exception from HRESULT: 0x8007000D) below is the web.config that I am using.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\Brochure_Fulfillment.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />

I'm getting an HTTP 502.5 error when trying to run my ASP.NET core 2.0 web app from IIS.
I've installed the .NET Core Windows Server Hosting Bundle and checked all my IIS settings as per this document https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/index?tabs=aspnetcore2x
The web.config looks like this.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\OscarWeb.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />
</system.webServer>
</configuration>
The Windows event log produces the following errors.
It is IIS v6.2 running on Windows Server 2012 R2. The web application was built using ASP.NET Core 2.0.
When I run dotnet from the commandline as follows there are no errors:
dotnet oscarweb.dll
The first thing you have to do in this scenario is to create the logs folder if it is missing and check the stdout logs generated.
It can be several different things but from personal experience the most common issue i had was IIS not having enough permissions to run it. In IIS you can configure the Identity used in Advanced Settings. If it is using ApplicationPoolIdentity then change it to LocalSystem and see if it works. The logs in the stdtout file however will give you the answer.
The solution to this problem (in my case at least) was to reboot the web server. After installing the .NET Core Windows Server Hosting Bundle you need to reboot the server for them to be registered correctly.
Thanks to Chris Pratt (first comment underneath my question) for suggesting the answer :)
Not sure if your webconfig is complete. I believe aspnetcore tag needs to have the ASPNETCORE_ENVIRONMENT environment variable set as well.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\OscarWeb.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" >
<environmentVariables>
<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="YourRuntimeEnv" />
</environmentVariables>
</aspNetCore>
</system.webServer>
</configuration>
