c# - Using Encrypt=yes in a Sql Server connection string -> "provider: SSL Provider, error: 0 - The certificate's CN name does not match the passed value."

Question

I'm using Encrypt=yes in a SQL Server connection string, as I need the TCPIP traffic to be encrypted, but on opening the connection I get an error:

A connection was successfully established with the server, but then an error
occurred during the pre-login handshake. (provider: SSL Provider, error: 0 -
The certificate's CN name does not match the passed value.)

Any suggestions how to fix this? I assume I need some sort of certificate relationship between my servers, but have no idea where to start.

I need this for two connections, one each to a SQL 2000 server and one to a 2005 server.

Answer 1

Your database connection can be configured to encrypt traffic and to accept any certificate from your server. Not a grand solution, but it worked for me.

The resulting connection string should look like this:

"[...];Encrypt=True;TrustServerCertificate=True"
