Hello,

 What is the specific error the browser is giving you? Does it allow you to bypass?
Is this a new environment setup for testing? If so would you be able to DM me credentials?

IE v11:

This page can’t be displayed 

Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://orchard4.bayviewphysicians.com  again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details), which is not considered secure. Please contact your site administrator.

I was able to access your website with IE11 of HTTPS no errors, what OS is your client/browser running on?

Yes, I can also log on remotely.   Only the internal web browsers throw the error.   You will have to do ConnectWise session to see the problem.  I assume you have access to my contact information.

I am suspecting that the problem is caused by a Windows update.   These have been installed:

4530689 - Dec 10, 2019 cumulative update 

4520724 - servicing stack 

4054590 - dot net 4.7.2 

4521858 - Servicing stack update 

3192137 - bundled in something else, not documented 

KB4054590 led me to this link. 

https://support.microsoft.com/en-us/help/4458166/applications-that-rely-on-tls-1-2-strong-encryption-experience-connect ;

I added the suggest registry key, and rebooted, without success.   Next moves will be to build a new configuration and block windows updates.
