    We have two customers that have tried installing UPS Basic v12.1.11.2439 and continue to receive the following error.

    Error: Unable to submit transaction to the UPS server. Please check the internet connection or contact your network administrator (Error connecting with SSL.
    EOF was observed that violates the protocol. Unable to POST to "https://onlinetools.ups.com/ups.app/xml/ShipConfirm" (Compatible)).

    It was working until last Friday. Has something changed?

    Thank you!

    UPS retired the last of their old servers. We had to recode for new SSL\TLS requirements.

    You will need the latest installer from our beta page, found here:

    Thank you,

    We set TLS 1.2 on in the Chrome Browser and it is now working. Will try that on our second customer too and let you know.
