Suddenly seeing connection failure error for PayPal transactions some times after the ColdFusion 2021 patch recent upgrade for log4j issue. Anyone facing this issue with your PayPal NVP services?

What are you using to connect to paypal? cfhttp or something more involved?

Using cfhttp only

If it involved one of the cf packages, I was going to recommend removing it and reinstalling it. We've had to do that frequently keep things functional on our end ever since Update3.

But have been seeing other random failures as well, so it wouldn't surprise me if that's going on with you too

@Sravani Do you see other cfhttp requests fail as well?
May I know the version of JDk you are using?

oh, there were some bugs in 11.0.1 and 11.0.2 surrounding certificate algorithms that led to some really weird behaviors with cfhttp. I would upgrade to a newer java.
