PHP CURL Error - curl: (56) Recv failure: Connection reset by peer

Question

basically, this error only occurs in CURL

curl: (56) Recv failure: Connection reset by peer

But when I visit it directly the link directly

Answer 1

I resolved this issue by removing whitespace characters from the URL. In my situation, it was the proxy server that was erroring out, not the web server.

In PHP:

     curl_setopt($ch, CURLOPT_URL, trim($url));
