wp_remote_get失败，并显示“从对等方接收数据时失败”

Question

I'm trying to get file contents of a file with this:

$google_fonts = (array)wp_remote_get( THEME_ADMIN_URI.'/google_fonts.txt' );

On var_dump($google_fonts); it prints this:

array(2) {
    ["WP_Errorerrors"]=> array(1) { 
        ["http_request_failed"]=> array(1) { 
            [0]=> string(41) "Failure when receiving data from the peer" 
        }
    }
    ["WP_Errorerror_data"]=> array(0) { }
}

This is the first time I see this. I'm on a support task on a foreign server and WP Installation, so I have limited access, especially to php and server settings. Path is good, and on my server and localhost, it works fine. File can be accessed directly in browser.

If I try to use file_get_contents() based on the local directory not the domain, it works.

Any ideas what's causing this?

我见过当请求的域使用CloudFlare时wp_remote_get（）失败-有关SSL如何混淆CloudFlare的wp_remote_get（）以及在正确配置SSL证书（站点和CloudFlare内部）时请求出错的问题。
