After the website has been built, we need to use ftp to upload files. For some novice webmasters, they may encounter the situation that the virtual host ftp cannot be connected. The common reasons for FTP connection failure are as follows:

1. An error in user name or password caused the connection to fail

For the security of the server, many virtual hosts prohibit anonymous connections. If the user name or password is wrong, the ftp connection will fail.

2. Domain name resolution problems lead to ftp connection failure.

When connecting to FTP, the address bar needs to fill in the domain name or IP address of the FTP virtual host. If the DNS domain name resolution is incorrect, we will not be able to get the IP address, so the connection fails.

3. The connection failed due to the problem of firewall setting.

The server's firewall settings can also cause FTP server connections to fail, so you can turn off the firewall or reset it, and then connect to see if you can connect successfully.

4. The connection failed due to the outage caused by the instability of the host

When the space you rent is in a state of downtime, you can't connect to FTP. You can use the PING command to test whether the server is in a normal condition.

5. Frequent connection to FTP for a short time leads to failure

If you connect to the FTP server frequently in a short period of time, it will be limited by the security policy of the virtual host, resulting in connection failure. You can try to connect after a while.
