Any follow up on this?
We had a client have the same thing. It stopped when Paya turned off TLS1.0 on 6/1, but just started working again on 6/7 after Paya turned it back on 6/6. So, we went through the process of updating their server & workstations to use TLS 1.2 & SED 2.0 on 6/20, but then the imports stopped working again.
Any idea if this is TLS or SED related? I am wondering if its their website TLS or if an import setting changed for the CreditCardGUID from SED 1.x to 2.0? They are on Sage v2016.
I would think TLS, but I don't think Paya turned the 1.0 back off yet, I thought it was going to be again on 6/30.
They are also able to process credit cards from Sage fine.
