I had some testing that was going well up until last week.

 

https://api-3t.sandbox.paypal.com/nvp gives error:

Secure Connection Failed

 

Is this a known issue? Need to finish up this project and move into production.

 

edited to update the correct issue, since I was testing variations in an attempt to troublshoot

Hi All,

This issue should now be completely resolved.

The URL should from today show the correct sub-domain "sandbox.paypal.com instead of "sandbox3.paypal.com".

Hello,

This isn't a known issue.

It appears your unable to establish a secure connection to our endpoint. Does your system support TLS v1.2 ?

You can test and confirm by using the TLS test tool available here - https://github.com/paypal/TLS-update

Thanks Justin. TLS was fine. Turns out the removal of GET from NVP/SOAP was the issue. I was quick testing some variations in cURL and browser with GET. Switched to POST and all seems to be good. Leaving this here in case anyone else needs to check up on more security updates https://www.paypal.com/au/webapps/mpp/merchant-security-roadmap
