Question

I ported my SQL Server DB from local to production environment and suddenly faced the following error during connect

System.Data.SqlClient.SqlException: 
A connection was successfully established with the server, 
but then an error occurred during the pre-login handshake. 
(provider: SSL Provider, error: 0 - A system shutdown is in progress.)

There is nothing special in Entity Framework connection string though:

... connectionString="metadata=res://*/EF.DataBaseModel.csdl|res://*/EF.DataBaseModel.ssdl|res://*/EF.DataBaseModel.msl;
provider=System.Data.SqlClient;
provider connection string='data source=server-ip\SQLEXPRESS2008R2;initial catalog=db;user id=user;password=password;multipleactiveresultsets=True;App=EntityFramework'"
    providerName="System.Data.EntityClient" />

What can be wrong here ?
Thank you in advance!

I found out that this error relates to a DB Cluster failover. Go to Failover cluster manager and check for cluster events/errors. You should be able to see the exact time when it failed over(even if the message only says ‘unexpected failover occurred’
