This article discusses why you may receive a “Too many connections from this IP” error message when you use FTP, and how to resolve the problem.
Despite the wording, this is not an IP address block. It is a per-client connection limit, and it clears as soon as you reduce the number of connections. If FTP will not connect at all, and other services such as mail and SSH are failing from the same network, see My IP address has been blocked instead.

​
Problem

When you try to connect to your account using regular FTP, you receive the following error message:

​
Cause

This error message occurs because FTP clients on managed hosting accounts are limited to a maximum of eight (8) simultaneous connections. If your FTP client exceeds this limit, you receive the error message described above.

​
Resolution

To resolve this issue, configure your FTP client to limit the number of simultaneous connections. The following procedure demonstrates how to do this for the FileZilla FTP client. If you use a different FTP client, please consult its documentation about how to limit the number of connections. To configure the maximum number of simultaneous FTP connections in FileZilla, follow these steps:
  1. Start FileZilla.
  2. On the File menu, click Site Manager:
    FileZilla - File menu
  3. Click the site entry that you want to configure, and then click the Transfer Settings tab:
    FileZilla - Transfer Settings
  4. Select the Limit number of simultaneous connections check box.
  5. In the Maximum number of connections box, select the maximum number of connections that you want to allow for the client. Make sure that this value is less than the server limit of 8 simultaneous connections.
  6. Click OK.
