Office365 Authentication Error

We are on a bit of storm lately due to TLS 1.0 and 1.1 being retired.

All our clients are experiencing a disconnection / authentication failure.

 

This was the link on a pop up error. https://go.microsoft.com/fwlink/?linkid=2161187.

 

We got 2 Windows Server. Ad-connect (2012 R2) and Domain Controller (2012) and windows 10 client

I followed the instruction Update 3140245

Download and install dot net

 

I add registry for TLS 1.2 using this https://docs.microsoft.com/en-us/windows-server/identity/ad-fs/operations/manage-ssl-protocols-in-ad-fs. (both client and servers)

 

But still nothing.


I am manually checking TLS 1.2 in advanced settings from internet options and it works (temporarily) but windows 10 automatically unchecking this options. 

 

Can anyone tell me if i miss or done something wrong ?
