Response: 421 Too many connections (8) from this IP

If your FTP client is using more than 8 connections at the same time, you'll get an error message similar to this:

Response: 421 Too many connections (8) from this IP
Error: Could not connect to server

Idle FTP Connections

Idle FTP connections are caused when an FTP client opens multiple connections without closing the previous ones, or due to an incorrect setting.

With VPS, Dedicated, and Managed hosting plans you can modify the number of simultaneous connections allowed in their WHM and the default setting is usually 8 or 10. Increasing this limit will prevent the error messages that we'll review later in this tutorial. Our Shared plans allow up to 8 simultaneous FTP connections from 1 IP address at a time, but you cannot raise this limit.

Viewing / Closing Idle Connections in cPanel

Step 1. Login to cPanel.
Step 2. Click FTP Session Control in the Files section.
Step 3. You will then see a list of all your current FTP connections. Click the Disconnect link in the Actions column.
Step 4. You will see a message similar to "Are you sure you want to disconnect testuser@example.com FTP user?." Click Disconnect to proceed.

 You are finished when you see a message like this:"The FTP session with PID 27510 was terminated. "
