我的脚本有问题。 我在Infomaniak（共享主机）中创建了一个网站 PHP脚本将文件发送到远程FTP服务器。
然后，我更改为另一台主机（也共享）：Swisscenter。 在该服务器上不起作用
这是相同的脚本，具有相同的登录名。 目标服务器上没有IP白名单
我使用PHP 5.6和7.0进行了测试，没有变化
这是错误：https://pastebin.com/ZSyVLtsF
Whoops, looks like something went wrong.

我不明白为什么它可以在第一台主机上运行，而不是第二台主机上运行 任何想法 ？ 谢谢
更新
这是FTP的PHP类：
namespace App\FTPManager;
class FTP
{
protected $host;
protected $port;
protected $timeout;
protected $connection;
protected $mode = FTP_BINARY;// FTP_ASCII;
public function __construct($host, $port = 21, $timeout = 90)
{
$this->host = $host;
$this->port = $port;
$this->timeout = $timeout;
}
/**
* @return mixed
*/
public function getConnection()
{
if (!$this->connection) {
$this->connection = ftp_connect($this->host, $this->port, $this->timeout);
}
return $this->connection;
}
public function login($username, $password)
{
return ftp_login($this->getConnection(), $username, $password);
}
public function upload($remote_file, $file)
{
return ftp_put($this->getConnection(), $file, $remote_file, $this->mode);
}
public function download($file, $remote_file)
{
return ftp_get($this->getConnection(), $remote_file, $file, $this->mode);
}
public function close()
{
ftp_close($this->connection);
$this->connection = null;
}
}
