Transferred from: http://www.zmland.com/forum.php?mod=viewthread&tid=941

Deploying the NET Core application in the IIS environment, under the default configuration, receives the following error if the task executes for up to 2 minutes (bad Gateway):

If you want to perform a long-duration task, you can modify the System.webserver/aspnetcore section of the published Web. config file to add the Requesttimeout property to it:

<system.webServer>  <aspnetcore requesttimeout= "00:20:00" .../></system.webserver>

Property Description:

• Requesttimeout
  The optional TimeSpan property.
  Specifies the duration for which the ASP. NET Core module will wait for the response of the process listening on%aspnetcore_port%.
  The default value is "00:02:00".
  Requesttimeout must specify an entire number of minutes, otherwise it will default to 2 minutes.
