Answer 1

It seems that your curl client is getting some response from server that it can not understand, Error#12 means: CURLE_FTP_WEIRD_USER_REPLY
here is the PHP Manual link: http://php.net/manual/en/function.curl-errno.php
and description of error: http://web.mit.edu/jhawk/mnt/ss.b/curl-7.10.5/docs/libcurl/libcurl-errors.html
You can use curl_error to capture the error How to catch curl errors in PHP
Other thing to consider here is your proxy, is it allowed to access the host and port you are trying to access and you access the host without proxy?

Answer 2

CURLE_FTP_WEIRD_SERVER_REPLY (8)
The server sent data libcurl couldn't parse. This error code is used for more than just FTP and is aliased as CURLE_WEIRD_SERVER_REPLY since 7.51.0.
CURLE_REMOTE_ACCESS_DENIED (9)
We were denied access to the resource given in the URL. For FTP, this occurs while trying to change to the remote directory.
CURLE_FTP_ACCEPT_FAILED (10)
While waiting for the server to connect back when an active FTP session is used, an error code was sent over the control connection or similar.
CURLE_FTP_WEIRD_PASS_REPLY (11)
After having sent the FTP password to the server, libcurl expects a proper reply. This error code indicates that an unexpected code was returned.
CURLE_FTP_ACCEPT_TIMEOUT (12)
During an active FTP session while waiting for the server to connect, the CURLOPT_ACCEPTTIMEOUT_MS (or the internal default) timeout expired.
