SQL error: : A connection was successfully established with the server, but then an error occurred during the login process.

SQL error: : A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error:0 – An existing connection was forcibly closed by the remote host.) (Microsoft SQL Server, Error: 10054)
We have one SQL 2012 Std server.
We build another new Windows 2012 R2 DataCenter Server to install SQL management Studio.
When we are trying to connect SQL DB server from new SQL management Studio, we are getting above error.
Please suggest.

Source: SQL DB Server OS: Windows 2012 R2 Data Centre
Source: SQL DB Server version: SQL 2012 Standard Edition
Destination Server: SQL Studio Installed on Server OS: Windows 2012 R2 Data Centre
Destination Server: SQL management Studio Version Build number:  15.0.18142.0

Most likely a TLS protocol mismatch.

Ensure your client side connection matches server side TLS protocols supported.

  1. All Application servers have the same VLAN. 
  2. All App servers are same OU.
  3. SCCM DB server is on separate VLAN, able to connect Application server but not Beacon server.
  4. TLS registry enable 1.2 in Beacon Server
  5. Installed SQL Native client in Beacon server
  6. Installed ODBC Driver in Beacon server
  7. Installed OLEDB Driver in Beacon server
  8. All relevant patches are updated in Beacon server.
  9. We take separate server and Installed respective software’s, even we get the same error on this server.
From here we are able to telnet, ping and trace route

Please suggest the next steps.
