IPN issue in version 2.6.11

All of my sites were working fine until December 2016
Now each of them shows
wp_remote_post() failed. PayPal IPN won’t work with your server. Contact your hosting provider. Error: cURL error 35: Unsupported SSL protocol version

I have contacted the hosting provider
They ran a paypal check :
curl https://tlstest.paypal.com
PayPal_Connection_OK

php -r ‘$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, “https://tlstest.paypal.com/”);
var_dump(curl_exec($ch)); var_dump(curl_error($ch));’ | grep PayPal_Connection_OK
PayPal_Connection_OKbool(true)

I have tried disabling all other plugins and same result.
