Exchange 2016 OWA is not opening on chrome.

I have just installed Exchange 2016 Version 15.1 ‎(Build 544.27)‎ ; even at the hosted server (windows 2016) I am unable to open OWA/ECP at google chrome Version 54.0.2840.99 m (64-bit).
Chrome says: ERR_SPDY_INADEQUATE_TRANSPORT_SECURITY

I am using SSL certificates: https://www.ssls.com/ssl-certificates/comodo-positivessl-multi-domain 
I am using the same kind of certificate protected exchange 2013 servers on chrome without any issue.

I have found the related links:

Take a look at these articles. Known issues with Exchange 2016 and Windows 2016.

https://blogs.technet.microsoft.com/exchange/2016/11/04/update-on-windows-server-2016-and-exchange-server-2016/

https://exchangeserverpro.com/dont-deploy-exchange-server-2016-windows-server-2016-now-due-stability-issues/

Recommendation is to install Exchange 2016 on Windows 2012 R2.

Thanks for the links.

As per the link you shared the issue comes when you configure DAG not in a standalone installation. I have also configured a standalone setup. My issue i guess is due to http2 protocol enabled by default. Pls guide me further.

If running a standalone Exchange 2016 on WS2016 without DAG, there should be no issues?

That’s correct.

Yes, no issue when Windows 2016 is used to deploy Exchange 2016 CU3 in non-DAG configuration. So I deployed on WS2012R2 to enable HA. Will wait patiently for the fix.

In the three separate lab scenarios I have--all Exchange 2016 CU3 stand-alone servers on Windows 2016 RTM--there isn't one that functions properly.

I'll probably stick with Exchange 2016 on Windows 2012 R2 in production for future installs until CU4/5.

I download and ran the IIS Crypto 2 tool, Clicked the best Practices button & hit apply, rebooted and all is fixed.
I don't know what the tool did; couldn't find the log report after the reboot.

Now I can open the owa/ECP at the chrome as well.
Though all looks cool & smooth now, I still cautious & in dilemma if I put it in production or not.
Though this server would be having up to 10 mailboxes & would be standalone for ever.

Mr. Todd Nelson gave the best recommendation. I agree with him.
As it's a small standalone installation, I dare to go with the existing plan.
The steps I performed fixed the current issue so I choosed my solution.
