Paypal - update to TLS 1.2

I received a notification from Paypal that my Dolibarr doesn’t comply with their new security mandate, and won’t accept payments after June 30th.

How do I change my Dolibarr to operate on TLS 1.2? … I did the change 3 or 4 years ago, that broke when they moved from SSLV3 . . . seems it’s happening again .

the requirements are at www.paypal.com/tls

Thank you for this amazing software! And any help in getting this running correctly!
