Hi,

        I'm using libcurl version of 7.52.1 with OpenSSL version of 1.1.0d
in embedded device. Sometime i'm noticing the curl error code 35 when
device trying to connect to production server --> "CURL ERROR Unknown SSL
protocol error in connection to xxxxxx.com:443". What could be the reason?
Since it is not occurring consistently it is difficult to do wireshark when
this error occur

            Please note that i disabled CURLOPT_SSL_VERIFYPEER and
CURLOPT_SSL_VERIFYHOST.

curl_easy_setopt(curl_handle, CURLOPT_SSL_VERIFYPEER, 0L);
curl_easy_setopt(curl_handle, CURLOPT_SSL_VERIFYHOST, 0L);

Thanks,
Gnana Guru N.
