DOMDocument Remote Load Error failed to open stream:permission denied how to handle

DOMDocument Remote Load Error failed to open Stream:permission denied what to do?
The code is simple. That's it...


$doc = new DOMDocument ();
$doc-Load (' http://223.4.174.61:22093/quoteFile/quote.xml ');

The error is as follows

Domdocument::load (Http://223.4.174.61:22093/quoteFile/quote.xml): Failed to open Stream:permission denied


Local testing is fine. , but not on the server.
The server tries to use fopen file_get_contents to prompt Permission denied, but open another remote connection is no problem.

Look for the gods of the road.

The server has disabled the open remote file

If it's not an autonomous server, most of them are banned.
