Error Message: An error occurred with the following error message: "Negotiation failed. The connection was closed by the server."
The most likely reason for this error is that the client needs to be upgraded to support the newer security protocols. You may not have upgraded the COZYROC SSIS+ suite in a few years so you have not picked up our support for the newer protocols. We suggest you upgrade to SSIS+ 1.9 to resolve this problem.
