Hi Ray,
I have been in contact with my hosting provider and told them your reply and they have replied thus:
On checking, I see that the "tls_version" enabled on the server is TLS 1.2, as the PayPal mentioned in the website

You can also check the same using the following command.
openssl ciphers -v | awk '{print $2}' | sort | uniq
Thoughts?
Best wishes,
John
