Chances are that while you've been using FileZilla you've also come across the ECONNREFUSED — connection refused by a server error. If that's the case — great that you've found this tutorial! I am going to show you three methods that might help you with resolving this FTP error.

可能是，当您使用FileZilla时 ，还遇到了ECONNREFUSED —服务器错误拒绝了连接 。 如果是这样的话，很高兴您找到了本教程！ 我将向您展示三种可以帮助您解决此FTP错误的方法。

第一种方法。 更改FileZilla的默认端口值 (First Method. Changing FileZilla's Default Port Value)

The error could appear due to using the incorrect port while connecting through FileZilla. In this situation, you just need to change the default FTP port to the default SFTP port number. Simply change 21 to 22 on the "Port" input box.

第二种方法。 禁用防病毒/防火墙 (Second Method. Disabling Anti-Virus/Firewall)

如果先前的解决方案无法带来预期的结果，您该怎么办？ 要解决该错误，您可以尝试更改FileZilla的网络配置：

• Connect to FileZilla FTP client, then go to "Edit" and then to "Network Configuration Wizard".

  连接到FileZilla FTP客户端 ，然后转到“ 编辑 ”，然后转到“ 网络配置向导 ”。

• When "Firewall and router configuration wizard" window appears, click "Next" to continue.

  当出现“ 防火墙和路由器配置向导 ”窗口时，单击“ 下一步 ”继续。

• As the Default transfer mode select "Passive (recommended)". Also, tick "Allow fallback to another transfer mode on failure" selection.

  作为默认传输模式，选择“ 被动(推荐) ”。 同样，勾选“ 允许失败时回退到另一种传输模式 ”选择。

• Choose "Use server's external IP address instead".

  选择“ 改为使用服务器的外部IP地址 ”。

• Select the "Get the external IP address from the following URL". Enter the default value in case the input field is empty and continue (default value is http://ip.filezilla-project.org/ip.php).

  选择“ 从以下URL获取外部IP地址 ”。 如果输入字段为空，请输入默认值，然后继续(默认值为http://ip.filezilla-project.org/ip.php )。

• Do not adjust the port range configuration and then choose the "Ask operating system for a port".

  不要调整端口范围配置，然后选择“ 向操作系统询问端口 ”。

At this point, you need to ensure that you've made correct configurations. Hit the "Test" button to let FileZilla try to make a connection to probe.filezilla-project.org and it will perform some simple benchmarks.

此时，您需要确保已进行正确的配置。 点击“ 测试 ”按钮，让FileZilla尝试建立与probe.filezilla-project.org的连接，它将执行一些简单的基准测试。

If the test goes without any failures, attempt to connect to your hosting account once more. It should work perfectly well. In case the "ECONNREFUSED" error repeats itself, you should try reaching out to your hosting customer support to get some help.

如果测试顺利进行，请尝试再次连接到您的托管帐户。 它应该工作得很好。 如果“ ECONNREFUSED ”错误再次发生，您应该尝试与托管客户支持联系以获取帮助。
