IIS 10 Coldfusion 11 served website won't load default home page on IOS mobile devices

Have a Windows 2016 server with IIS 10 running ColdFusion 11. Certain websites (with https://) won't load the default home page on iPhone and iPad only. The default home pages load great on all browsers on Windows 10, and even on a Mac in Safari and Chrome, but won't load on iPhone and iPad in either Safari or Chrome -- they just time out. If I put the name of the default page in the URL, it will load just fine on these IOS mobile devices, but if I just use the site's domain name, it will NOT load. IOS versions are up-to-date. If we set the default page to an html page it WILL load; if we set it to a cfm page it WILL NOT load.

So the FAILING situation is in loading default cfm page on iPhone or iPad.

I have come up with a workaround for this problem.

I created an index.html file containing:

<meta http-equiv="refresh" content="0;URL='https://domainname.com/index.cfm'" />

and made index.html the default page for the website.

I don't like it, but it seems to get things working on the iPad and iPhone.

Anyone have any suggestions?  Thanks!

This problem does not occur with IIS 6 on an earlier server operating system.  Only with IIS 10 on Windows Server 2016.

We are experiencing this too. We have IIS 10 and ColdFusion 2016. Any solutions?

This is apparently a bug in Safari version 9 and newer.  Affects ColdFusion running on Windows Server 2016, but also other applications (reported by other developers of ASP, ASP.net and NGINX.)

Detailed here:

http://www.giancarlogomez.com/2016/05/coldfusion-iis-10-http2-safari-bug.html

https://tracker.adobe.com/#/view/CF-4198446

Temporary fix (disable http2 on Windows Server 2016 in the registry):

- Open the registry editor (regedit)

- Browse to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters

- Enter 2 new DWORD Values EnableHttp2Cleartext and EnableHttp2Tls

- Set their values to 0

- Reboot

I believe this was resolved with iOS 11. We had this issue but after upgrading to iOS 11, I could no longer reproduce this issue.
