SQL Server access issue I am trying to connect 3 SQL servers using SSMS from a different landing server. The issue is I am able to connect 1 server but unable to connect other 2. The error I get is below:




  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.)


I am unable to figure out what is wrong with other 2 servers and need your help.

Landing server details:


Windows server 2008 R2 Ent Edition
SSMS 2012 SP1


SQL server details:


SQL Server 2012 -- Able to connect
SQL Server 2012 -- Unable to connect
SQL Server 2005 -- Unable to connect


I am able to ping and telnet all 3 servers from my landing server. Also, tried SQL authentication for 2 servers which I am unable to connect but it didn't work. Disabled TCP chimney, didn't work. The same 3 connections are working fine from my other landing server. So not sure what is wrong with this one. Please help me out to fix the issue.
You need to check your SSL and TLS settings.

Check out this KB 3135244. The settings between the client and server should be somewhat consistent (i.e. if the server only allows 1.2 and the client only supports 1.0 I think you might run into issues). Also read through the known issues on that page

Updating to a build that supports TLS 1.2 might resolve your issue.
