Hello, First, I apologize - this is posted in the wrong forum - for some reason it will not allow me to post in the proper forums - if someone is able to move this to the right location, I'd appreciate it! I had configured a test environment using manager.paypal.com for a payflow pro workflow. Everything was working just fine using pilot-payflowpro.paypal.com, and creating a URL that linked to payflowlink.paypal.com with the MODE=test parameter. However, a couple of days ago, I started getting the following error posted back to my error URL: Failed to connect to host Input Server Uri = https://pilot-payflowpro.paypal.com:443 This error shows up after the hosted checkout screen at https://payflowlink.paypal.com/?SECURETOKEN=[redacted]&MODE=TEST, once the user attempts to log in with a sandbox account, or after entering credit card details. I first attempted to change settings to use https://pilot-payflowlink.paypal.com/?SECURETOKEN=[redacted], but the results are exactly the same. My code is configured the same for our production environment, which has been working without issue this entire time. Searching the internet for this error, it seems to suggest my server doesn't support TLS 1.2 - however, it absolutely does, and there should be no "callback" to my server at this point, as this error occurs right in the middle of the PayPal-driven checkout flow. It's taking quite a long time to hear back from MTS support, so any insights or thoughts from the community about this would be helpful. Thanks in advance!
