How to solve the problem of FileZilla_Server:425 Can't open data connection

When installing FileZilla Server on the server, the 425 Can't open data connection problem occurs and the client fails to read the directory list

The server is from Tencent Cloud. The specific solution is as follows

This problem is mainly due to the network environment where the server is located. To solve this problem, it is very simple:

1. Enable Passive Mode in FileZilla Server service software and set the specified port address range, such as 60000-60020. If there are many users, a larger port range is fine.

Note: After enabling Passive Mode, we do not need to select USE the following IP and fill in the external IP.

2. Then allow the TCP ports used by FileZilla Server on the system firewall of the ftp server, such as 21,60000-60020, or allow specific programs such as E:\Program Files\FileZilla\FileZillaServer.exe .

Add both outbound and inbound rules

3. If you are using Alibaba Cloud or Tencent Cloud Server, you need to add the corresponding port to open in Cloud Server Instance->Set Security Group Rules. Add both the inbound and outbound

After setting, connect to FTP again to successfully obtain the directory list

The above is the solution to the FileZilla Server: 425 Can't open data connection problem. I hope it will be helpful to everyone.
