We recently put our CF 2016 and MS Server 2016 online for production. While checking for self-induced errors, several external checking tools show that our site is not configured for http/2. Redirects for http to https are in place as are the proper SSL certs. No errors discovered there.
Local tests, suggested on internet posts, do show we are configured to serve http/2 and log files show the same. However, looking at our jakarta redirect urls on the IIS logs may indicate that http/2 are being converted to http/1. The Tomcat log shows, virtually, every query as http/1.
Is there anything that I am missing on either IIS 10 or CF 2016 settings?
