We currently have a client program that sends xml data to a vendor website. This worked fine when the website accepted data using the TLS1.0 format. On July 1, 2017, the vendor no longer supported TLS1.0 and we were informed that to continue sending data it would need be sent using TLS1.2 format only.
When we now try to send the xml data, we get the following error:
The underlying connection was closed: An unexpected error occurred on a send.
Any suggestions to resolve this error in PB12.5 classic or we can upgrade to PB2017 if there is an easier fix in that version?
