PayPal TLS test failed
<p>I have confirmed my server is supporting tls1.2 with the help of following command.</p>

<pre><code>openssl s_client -connect shop.domain.org:443 -tls1_2
</code></pre>

<p>The above command returned a certificate chain and handshake.</p>

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

<pre><code>curl https://tlstest.paypal.com
</code></pre>

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

<pre><code> wget https://tlstest.paypal.com

<p>Can somebody explain me why my test with PayPal is failed?</p>
