FileZilla is a great free FTP solution, which has been very useful to me for the last few months. However, after updating to 3.2.0 I started getting the following error: 421-too-many-connections-8-from-this-ip
I got rid of it, by Opening the Site Manager -> Transfer Settings then ticked “Limit number of simultaneous connections” and put “1” for the Maximum number of connections. Obviously, this solves the problem because it limits the allowed connections by FileZilla Client to 1.

this really helped out thank you, alot of forums in the searched i did and this
was to the point and exactly what i was looking for so thanks again
