I have this code
if(ereg("^(https)",$url))
curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,false);
// execute, and log the result to curl_put.log
$result = curl_exec($curl);
$error = curl_error($curl);
The error specified is
SSL read: error:00000000:lib(0):func(0):reason(0), errno 104
Any ideas on the cause
I encountered a similar cryptic error while working with a third-party library. I tried the CURLOPT_SSL_VERIFY[PEER|HOST]
but it made no difference. My error message was similar:
SSL read: error:00000000:lib(0):func(0):reason(0), errno 54
So I visited http://curl.haxx.se/libcurl/c/libcurl-errors.html, looking for the error code 54.
CURLE_SSL_ENGINE_SETFAILED (54) Failed setting the selected SSL crypto engine as default!
This was wrong though - I was making other HTTPS requests using curl in other parts of the application. So I kept digging and found this question, R & RCurl: Error 54 in libcurl, which had this gem:
The output you see is from lib/ssluse.c in libcurl's source code and the "errno" mentioned there is not the libcurl error code but the actual errno variable at that time.
So, don't let the output of curl_error() mislead you. Instead, use curl_errno() to obtain the correct error code, which in this case was actually 56, CURLE_RECV_ERROR. Had the wrong host name...
