HTTP request failed! HTTP/1.1 505 HTTP Version Not Supported error

Question

I\'m trying to use file_get_contents() to get the response from a server and this error was encountered. Could someone tell me what is the reason and how to fix

Answer 1

I ran into the same issue and in my case the culprit was an errant newline/CRLF character at the end of the request URL, which does not get caught by urlencode() (or maybe it does encode it but it still causes the server to produce the error). Once I found the problem the requests began to work again, even without the stream context options.

Hopefully this will help others.
