PayPal TLS test failed

Question

I have confirmed my server is supporting tls1.2 with the help of following command.

openssl s_client -connect shop.domain.org:443 -tls1_2

The above command returned a certificate chain and handshake.

But if I check the same with Paypal it failed with following errors. I have executed it from my server.

curl https://tlstest.paypal.com

curl: (35) Unknown SSL protocol error in connection to tlstest.paypal.com:443

 wget https://tlstest.paypal.com

Can somebody explain me why my test with PayPal is failed?

Answer 1

To fix this issue I have modified code to the following

# php -r '$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "https://tlstest.paypal.com/"); var_dump(curl_exec($ch));'

and it returned a value like

PayPal_Connection_OKbool(true)
