"SSL Provider, error: 0 - An existing connection was forcibly closed by the remote host" error when launching Controller client

Troubleshooting

Problem

System was initially working OK (no problems/errors).

Customer then modifies the Microsoft networking TLS settings (on both the Controller application server and SQL database server) so that:

TLS 1.0 disabled
TLS 1.1 disabled
TLS 1.2 enabled

After making those changes, user launches Controller client. User then:

Chooses database
Types in username/password

An error appears.

Symptom

System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Data.SqlClient.SqlException: 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.) ---> System.ComponentModel.Win32Exception: An existing connection was forcibly closed by the remote host
