Hi,
To mitigate the security issues for older protocols, we are trying to make our SP2013 foundation server to support TLS 1.2. We are facing multiple problems:
1) I am having custom timer jobs & event receivers which connect to another SQL Server 2014 which is configured to accept only TLS 1.2 connections. Here the connection is failing with error:
Error Message: SqlExceptionException Type: System.Data.SqlClient.SqlException
Error Location : 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.)
2) Please suggest how can we change the target framework to 4.6.1. I tried to change it through project properties and re-compile, but it does not show 4.6.1 Only 4.6 is allowed for selection (VS2017) (and I have all the frameworks installed).
I tried making changes as per this post, but now the target framework drop-down is blank, in properties window.
3) Apart from this, I need to know if we perform the TLS 1.2 related changes on the server (hardening), why the SharePoint stops working.
Please help in understand/overcome these issue.
Regards, Nayan
