I have an ASP.NET application running on IIS 8.5 that times out at 60 seconds regardless of what I set. In other words, I can set the connection timeout to 300 seconds or 30 seconds and the page will still time out at 60 seconds. The Request status code is 504 GATEWAY_TIMEOUT . Site: Connection timeout = 300 seconds (5 mins) Session timeout = 20 minutes Script timeout = 10 minutes App Pool: .NET CLR v4.0 Integrated pipeline 64-bit (32-bit not allowed) Idle timeout = 20 mins (default) Other things I've done: Read just about every article I can on this subject Set the executionTimeout in my web.config Restarted the site or ran iisreset after each change Disabled all sites except this one to isolate it Created a simple ASPX page in which I set a Sleep thread to under or over 60 seconds, and tried every combination with the connection timeout value. I'm at a loss. Any ideas?

IIS 8.5 connection timeout is _always_ 60 seconds

I have an ASP.NET application running on IIS 8.5 that times out at 60 seconds regardless of what I set. In other words, I can set the connection timeout to 300 seconds or 30 seconds and the page will still time out at 60 seconds. The Request status code is 504 GATEWAY_TIMEOUT.

Site:

Connection timeout = 300 seconds (5 mins)
Session timeout = 20 minutes
Script timeout = 10 minutes

App Pool:

.NET CLR v4.0
Integrated pipeline
64-bit (32-bit not allowed)
Idle timeout = 20 mins (default)

Other things I've done:

Read just about every article I can on this subject
Set the executionTimeout in my web.config
Restarted the site or ran iisreset after each change
Disabled all sites except this one to isolate it
Created a simple ASPX page in which I set a Sleep thread to under or over 60 seconds, and tried every combination with the connection timeout value.

I'm at a loss. Any ideas?
