How to Fix Error 421 Too Many Connections (8) From This IP

I just changed web hosting account recently but I still using the existing web hosting provider because this new web hosting will be hosted on an another domain name, so I need to upload all the necessary files to new web hosting again.

Normally I prefer using Filezilla to upload or download files, but sometimes I will found some error like 421 too many connections (8) from this ip. This may sometimes be accompanied with a “Delaying connection for 5 seconds due to previously failed connection attempt” error. So how to solve this type of problem? Do you ever see this error before?

When you see error 421 too many connections (8) from this ip, then you go to File > Site Manager. Select “Transfer Setting” tab, and then simply click on the checkmark box next to “Limit number of simultaneous connections” and you can keep “1″ in the box. (refer below image)

After you have limited the number of simultaneous connections to 1 but you still get the error 421 too many connections (8) from this ip, switch of your modem and on it back, and you may need to completely shut things down so the previous connections are killed.

Important: Don’t download thing when you upload or download files using Filezilla. and don’t surf net using browser too. Normally I seldom get the error 421 too many connections (8) from this ip.
