How to Resolve too many connection in filezilla with out setting up site manager manually??

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

Deposition

l published a detailed answer about this problem in general, which might be helpful to someone – Unstudied

I was getting this for the first time last night, and I tried everything from clearing idle connections in CPanel (on remote) to changing every setting possible in Filezilla. I resisted resetting my modem (which was PDANet in USB mode on my phone, in my case), but finally, I switched to Wi-Fi tethering, and now it works. I'm not saying PDANet/USB doesn't work, since I've been using it for years with no problem. But resetting my Wi-Fi connecting definitely did work. – Heartbeat

Answer 1

I was able to resolve my issue by changing the encryption setting in site manager under the general tab to only use plain ftp (insecure). Prior to that no matter what settings I selected I would get a time out error. I had been able to connect once or twice but while transferring would get a "421 Too many connections (8) from this IP Error"

I was getting the same error. To solve it in Filezilla, I had to change "Protocol" to "SFTP - SSH File Transfer Protocol" and now I can connect. – Feint

@JuniorMayhé, that only works when SFTP is available. For example, I just started getting this problem this year with my GoDaddy shared hosting accounts. These accounts do not have SFTP available. I think something has changed with GoDaddy. – Heartbeat

My case: 200k files transferred between Desktop A and Server B, Ubuntu on both. Install openssh-server on Desktop A, FileZilla on Server B. In FileZilla connect via SFTP and start the transfer. Originally used vsftpd hence here. – Algo

Answer 2

Sometimes FTP connections do not terminate properly and must be manually disconnected. We can do this in the cPanel under FTP Session control.

Instructions:

1. Login to your cPanel
2. Scroll down the menu until you find "FTP Session Control" or "FTP Connections".
3. You will see a list of your connections. Click on the button in the DISCONNECT column as long as the status of the connection states IDLE. You might have to click on the DISCONNECT button several times to remove all of the connections.

Just make sure that you clear out all of the connections listed and then try logging again. I did just go in myself and clear the connections. The connections should clear out when you disconnect from FTP.

Also, see a full article on the 421 Too many connections error. It explains how to view, close, and limit simultaneous connections within FileZilla.

This answer is helpful, but doesn't really solve the problem. Although you can clear concurrent FTP sessions in CPanel using these instructions, it doesn't stop Filezilla from creating more concurrent sessions. When you resume an FTP download in Filezilla, those sessions will begin to pile up again, and within minutes, you will encounter the error again. So, do you keep refreshing the CPanel page, and removing login sessions? You'll get tired of doing that pretty fast. – Heartbeat

Answer 3

When you are getting this mesaage " Response: 421 Too many connections (8) from this IP Error: Could not connect to server" in Filezilla it means that multiple connection are accessing in your FTP.

To avoid this problem you need to change the Filezilla settings. Follow this steps:

1. Open FileZilla.
2. Access the Site Manager.
3. Click on Transfer Settings tab
4. Check the box for Limit number of simultaneous connections, and set the Maximum number of connections to 10 or more.
5. Click the OK button. Now when you are using FileZilla, it will not allow you to go over your limitation of 8 simultaneous FTP connections.

Although I have seen this answer posted elsewhere, it did nothing to help me from getting the "Too many connections (8) from this IP" error with Filezilla. I checked the Limit box, and set my connections limit to 1. I don't know why it didn't stop the multiple concurrent connections, but using CPanel->Files->FTP Connections, they still accumulated. – Heartbeat

Answer 4

Most probably there's some firewall or NAT router interfering with orderly connection shutdown, silently dropping connections as opposed to informing both peers.

Inoperative

Answer 5

Go to the site manager, click the "transfer settings" tab, the check "limit number of simultaneous connections". Make sure the maximum number of connections is larger than 1 and smaller than 8.

Answer 6

The problem may be something like Romano mentioned. In my case, it happened while trying to connect to the FTP after multiple "20 seconds of inactivity" timeouts. It might have kept all those attempts as a connection and it said "too many connections."

The solution I found was to unplug the data cable and reconnect it. That closed all FTP connections "stuck" behind the scenes. I am in no way a pro in this field to explain exactly what happened, but it makes sense and it worked.

There may be other solutions. Here is a reference link.

Edit: It kept saying "20 second..." timeout, so I tried different settings. The one that worked was "Use plain FTP (insecure)" option. The host this website is using is Bluehost.

Some web hosts, such as GoDaddy shared/Linux, will refuse a request from plain FTP (insecure). – Heartbeat

Answer 7

Dropping the internet connection cleared the problem. I power cycled the wifi router and it all worked fine.

Answer 8

FileZilla 3.49.1

I know this is an old thread, but I thought I would provide the following update based on a more recent version of FileZilla.

This is how I ended up resolving the issue:

Edit > Settings > Transfers > Concurrent transfers >

Maximum simultaneous transfers: 8

Limit for concurrent downloads: 8

Limit for concurrent uploads: 8

I found that only setting the Maximum simultaneous transfers to 8 did not resolve the issue when uploading files. My previous settings were:

Edit > Settings > Transfers > Concurrent transfers >

Maximum simultaneous transfers: 8

Limit for concurrent downloads: 0 (no limit)

Limit for concurrent uploads: 0 (no limit)

My understanding of these settings is that the above configuration should resolve the issue as others have stated, but it's possible there is a bug or miscommunication of how this feature performs in the version I am using.

I'm not sure what other test conditions such as downloading and uploading simultaneously would do, but I believe the most reliable settings would likely be the following:

Edit > Settings > Transfers > Concurrent transfers >

Maximum simultaneous transfers: 8

Limit for concurrent downloads: 4

Limit for concurrent uploads: 4

Let me know if I'm wrong, I'm just reporting as to what seemed to have worked for me, and assumptions I've made based on those experiences.

I was hopeful that this would work. Alas, I get the same error. – Heartbeat

Nice try, but alas, this did not stop the problem with at least two of my (GoDaddy shared hosting) downloads. I should note that I get the problem with WinSCP client, also. – Heartbeat

Those config changes should be made with the understanding of ftpd config running on the server. – Algo

Answer 9

I was facing same issue. As it is showing new software available. Error resolved after installing new update, that is 3.22.2.2

Answer 10

Just change your ip via proxy or if you are using dynamic ip, just restart your internet device .. No need to change setting of filezilla or hosting server. :)

FileZilla 3.52.0.5, and problem still there. – Heartbeat

Answer 11

You can update "MaxClientsPerIP" in pure-ftpd config file which is situated on "/usr/local/apps/pureftpd/etc/pure-ftpd.conf" as many you want. Don't forget to restart your pureftpd service.

Answer 12

It means, that 8 users have connected to the same FTP-account. As far as the limit for simultaneous users connection is 8, everything which is more than 10 is blocked by an FTP-server. As a result - you can`t connect to the FTP-server
