Describe the bug

I am encountering a strange problem.

In our application I have a single controller where PUT, DELETE, POST getting 405 error
while the rest of controllers are working properly.

here is how my Web.Config is:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
		<handlers>
			<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
			<remove name="WebDAV"/>
		</handlers>
		<modules runAllManagedModulesForAllRequests="true">
			<remove name="WebDAVModule"/>
		</modules>
		<aspNetCore processPath="dotnet" 
					arguments=".\WebUI.dll" 
					stdoutLogEnabled="false" 
					stdoutLogFile=".\logs\stdout" 
					hostingModel="inprocess" />
		<httpProtocol>
			<customHeaders>
				<clear />
				<add name="Access-Control-Expose-Headers " value="*"/>
				<add name="Access-Control-Allow-Origin" value="*" />
				<add name="Access-Control-Allow-Methods" value="*" />
				<add name="Access-Control-Allow-Headers" value="*" />
				<remove name="X-Powered-By" />
			</customHeaders>
		</httpProtocol>
    </system.webServer>
  </location>
</configuration>
<!--ProjectGuid: B10BA5B4-B02C-4528-9272-8478A9F7B038-->

Here is my startup.cs

// configure services
        #region CORS

        services.AddCors(options =>
        {
            options.AddPolicy(
                AllowedOrigins,
                builder =>
                {
                    builder.AllowAnyOrigin()
                        .AllowAnyHeader()
                        .AllowAnyMethod();
                });
        });

        #endregion

// under configure
    app.UseCors(AllowedOrigins);

From controller I am getting this Response header:

    [HttpPut("save")]

        => await Mediator.Send(request);
}

angular service:

post<TPost, TOut>(url: string, param: TPost): Observable<TOut> {
    return this
      .http
      .post<TOut>(url, param, this.buildHttpOptions())
      .pipe(catchError(_ => this.handleError(_)));
  }



  private buildHttpOptions(): { headers: HttpHeaders; } {
    return {
      headers: this.buildBaseHeaders()
    };
  }

  private buildBaseHeaders(): HttpHeaders {
    const lang: string = 'it';
    const user:string = STRING_EMPTY;
    const datow: string = STRING_EMPTY;
    return new HttpHeaders(this.GetHttpHeaderObject(user, lang, datow));
  }

Can you try issuing the request with curl to see if it works that way? I suspect that your client app is not using the correct path but I don't know angular so this is just a guess. But if we can confirm that the endpoints work from curl that would point in that direction.

Hi,
here is an example :

curl -v 'POST' \
  'http://10.1.1.112/control-tower/api/reports/meat-monitor' \
  -H 'accept: text/plain' \
  -H 'Content-Type: application/json' \
  -d '{
  "warehouseCode": "066"
}'
* Could not resolve host: POST
* Closing connection
curl: (6) Could not resolve host: POST
*   Trying 10.1.1.112:80...
* Connected to 10.1.1.112 (10.1.1.112) port 80
> POST /control-tower/api/reports/meat-monitor HTTP/1.1
> Host: 10.1.1.112
> User-Agent: curl/8.6.0
> accept: text/plain
> Content-Type: application/json
> Content-Length: 28

The endpoint is visible on swagger:

same api on other server works fine

curl -v 'POST' \
