Connection Error

[romiluv4u]

We recently started getting errors for CIM profile transactions while connecting to Authorize .Net in production environment. The error that we are getting is: The underlying connection was closed: An unexpected error occurred on a send.

It was working perfectly fine few days back and no changes have been made to the production code. Amy insight to this issue will be very helpful.

Server used: Windows Server 2008 SP2

Application environment: .NET 3.5

Hello @romiluv4u

You will need to upgrade your platform to support a TLS 1.2 connection.  Please see our TLS FAQ for more information.

Thanks Richard. I was able to do the upgrades and now getting successful connection with Sandbox environment but authorize .net production is still throwing the same error.

Hello @romiluv4u

Which endpoint are you using?  If you're using https://api* or https://secure*, please try switching to api2  or secure2.
