How can I tell if our transmissins are using TLS 1.2

Hi everyone
Are you sitting comfortably
Then I will begin
We "moved" to TLS 1.2 quite a few months ago
Last June, ups required us to send our manifest transmissions to a new end point
One that would ONLY accept transmissions using TLS 1.2
This past weekend we performed an ipl
No updates
Just an ipl, followed by a number of file RGZPFM's
Since Monday, we are unable to successfully transmit to the new end point
The job log shows the message
3426 SSL_Handshake failed█ with RC code 0

I tried googling
3426 SSL_Handshake failed
But didn't find anything
I am waiting to hear from someone at ups, but it occurred to me
Are we no longer transmitting using TLS 1.2?
We are on V7r3
Does anyone know how I can tell if we are transmitting using TLS 1.2?
