How to Limit Simultaneous FTP Connections in FileZilla
When too many FTP connections cause access or upload issues. This article explains how to limit simultaneous connections in FileZilla.
By default, FileZilla is configured to transfer 5+ files at a time, which means that each time you make a transfer, the application will initiate 5+ simultaneous connections to the server.
If you are hosted on a shared server and trying to transfer many files, the server firewall may block your IP address due to an excessive number of simultaneous connections from one and the same address.
There is an easy way to reduce the number of simultaneous connections and transfers in FileZilla.
To reduce the number of simultaneous transfers, open the application -> Edit -> Settings -> Transfers. There you will see a field called Maximum simultaneous transfers - change the value to 1 and click on OK to save the changes.
