@slowreader and @patton: Ok, then you should contact your internet provider support.

@martin: I can connect with my phone hotspot but not my wifi which is xfinity.

I just now cleared all my history on Firefox and tried again to log into CPanel. Again the hourglass icon, but finally this message came up. (I am the website owner so I have no one to inform!) Thanks - Dan

I have a ticket opened at Simply Hosting, which hasn't changed. I've used them for years. It's my internet provider that has changed (formerly Xfinity aka Comcast Business, now Breezeline fiber optic). The web host says everything is working fine at their end, but WinSCP can't connect, nor can I log in to Simply Hosting's Cpanel using Firefox or Chrome. When I paste the url into the search line of the browser, nothing happens except I see the hourglass figure as the browser tries to find it. I have used both these ways to manage my website several times a month for twenty years or more. Thanks! - Dan

@slowreader and @patton: You should contact your hosting support. Also make sure you are using the correct protocol. Maybe the new hosting uses SFTP (or encrypted FTP), not plain FTP. Can you connect with any other client?

I have to switch to my phone hotspot for it to load.

patton

2024-03-31 20:51

Well my FTP won't load so that's all I have to do?

slowreader

2024-03-31 20:30

Same way I tried to do it last month: loaded up WinSCP, clicked on Log in, and instead of logging in, I got the message "Timeout detected. (control connection) Connection failed." Similarly, I can't access the website by going to cPanel with my web browser Firefox or the backup Chrome. I have no problem looking at my web pages online, and Simply Hosting support says "cpanel url is working fine". But I can't update the website, as I do every month at this time.

patton

2024-03-31 18:44

how did you do it

slowreader

2024-03-31 18:38

Yes, it worked fine, every month for many years. (Well, a few hiccups along the way.) Breezeline became active on Friday, and this is the first time I've tried to ftp or to reach cPanel since.

patton

xfinity

2024-03-31 18:32

did it work when you had xfinty?

slowreader

same here

2024-03-31 13:24

I am having the identical problem this morning after many years of updating my website at the first of every month.

Timeout detected. (control connection)
Connection failed.

My internet provider was Xfinity (Comcast Business). Last week I switched to Breezeline. Could that have anything to do with today's failures?

Thanks! - Dan

Re: Forcing IP In Passive Mode

2024-01-04

@LukeNe: Thanks for your post. The "Force IP address for passive mode connection" can help only if the IP address in the PASV command response is not correct IP address of the server. What is probably your case, but not in this thread.

LukeNe

Forcing IP In Passive Mode

2024-01-02 07:14

Just wanted to add my 2 cents – forcing the IP in passive mode solved my problem. Can now connect and ignore all of the above issues since the start of this post.

@martin: 10.240.101.27 is the FTP server. For my use I am only able to use FTPS for what I am setting this connection up for. Also no I am not able to use FTPS with any other FTP client.

Re: Need FTPS assistance

2023-07-28

@Unknown_Techy: What is the 10.240.101.27 IP address? Is the the correct IP address of the FTP server you are connecting to? Can you retrieve the directory listing or transfer files using any other FTP client with the same FTP server? If you can, post its full log file (as well a a full log file of WinSCP).

Found the issue and the solution for it.

2023-07-08 07:27

I figured out how to make sure proper passive IP should be passed so you don't have to go and change settings in Environment to "ON".

I inherited this server from someone who used to work here. Didn't know what the FTP setup was.

Anyway, here's the solution, I'm running PureFTPd please find something similar for your FTP service.

sudo echo "40110 40210" > /etc/pure-ftpd/conf/PassivePortRange

Restart pure-ftpd

sudo service pure-ftpd-mysql restart

If you are using AWS like me, you need to run

sudo echo "YOUR_EXTERNAL_IP_ADDR" > /etc/pure-ftpd/conf/ForcePassiveIP
sudo service pure-ftpd-mysql restart

@martin. Thanks for your time and help. Really grateful.

Johann

2023-07-05 16:04

@martin. I can't figure out either. Why is that ip being used to connect when the public ip is being given explicitly.

martin

Re: Comparison logs

2023-07-03

@Johann: So what is the 3.7.235.55 IP? It's not a private network IP. So how is it related to your FTP server, which is on a public IP 13.234.88.80?

Johann

Re: @anotherusername solution finally worked.

2023-06-19

@Johann: Please post session log files both with the default settings (not working) and your custom settings (working).

Johann

@anotherusername solution finally worked.

2023-06-15 08:06

Well the solution by @anotherusername of changing Auto to On worked but, What about other users who want to try to login through FTP and don't know of this? How can I solve this issue where it isn't relying on the client making changes on their side? I have another server similar to this one as they're made from the same custom AMI but for some reason only this one has this FTP login issue.

sarawgeek

2021-08-20 06:43

For me it was a VPN issue, server was blocking the IP so it was not allowing the directory listing, just check if you something similar kind of setup.
I was trying to connect from USA and server was in India, so may that is why it was blocking for security purpose.

fometeo

425 or MSLD are not the problem

2020-03-27 17:01

On a recent case the problem was not the lack of FTP server support for MSLD as log seemed to show cause the connection was lost just after MSLD trying to get the dir listed. The Linux vsftpd server was good:
at file /etc/vsftpd/vsftpd.conf it had both active and passive services OK

connect_from_port_20=YES
pasv_enable=YES

The issue did not happen all the times, sometimes the connection was established (!)

This was a CentOS 7 policy (SELinux) issue solved by

setsebool -P ftpd_connect_all_unreserved 1

or just disabling SElinux

By the way old Windows up to version 8 had ftp.exe supporting only active FTP.

anotherusername

My Solution!

2019-10-15 00:34

After messing around for ages and reading all the useless advice – this is what fixed it for me.
I am using Plesk FTP server with WinSCP connecting on port 21 Passive.
So in Sire settings – Go Advanced > Then FTP under Environment.
Change the following commands that used to be set to AUTO
Use MLSD command - On
Force IP for passive - On
Use HOST command - On

Boom then everything worked.

FTP connection and folder listing

2019-02-05 12:38

Hi,

I am facing this same issue am assuming if it's because the data channel ports 5000-5005 which i have updated the firewall settings which aren't open, It connects to the FTP successfully but does not list the folders under the FTP drive created.

Timeout detected. (data connection)
Could not retrieve directory listing
Error listing directory '/'.

Appreciate your input in this regard.

Thanks,

WinSCP error

2017-05-04 14:27

Hi All,

This could be caused if the server is in active mode and not in passive mode

Response:             227 Entering Passive Mode (202,234,195,227,219,190).

This is bit confusing. The numbers in the 227 response are not port numbers! Only the 219 and 190 represent a port number 56254 (219 * 256 + 190). The 202,234,195,227 is an IP address. So there's only one port number in the message.

2016-06-08 08:52

Try disabling passive mode. Probably not all FTP passive ports are not opened.

For example these all ports must be allowed to use passive mode.

Had a problem with this for years.
Forgive my "layman's" jargon.
Previous dialogues with site Admin & Tech personnel tried to locate a "problem" with my modem. That ceased when exactly the same "problem" arose with a different ADSL2 modem.
Was a problem then with my broadband connection, which used a shared, not dedicated, address at the exchange.
However, the problem was *only* with remote servers run on Microsoft Windows and was dated to a server upgrade ~3.5 years ago.
Other remote servers e.g. Unix didn't care
Once I changed providers, the problem disappeared altogether.
Until now.
It seems to be a connection speed? issue. I have blown my 2 gigabyte allocation and the transfer speed slows to around 7 kbs.
Logging on to the remote Microsoft Windows FTP server I got no timeout message but:

Could not retrieve directory listing -Can't open data connection

I deselected passive mode and removed permanent caching and, bingo, got in.
Hope this helps,
Laurie

Since 4.3 the passive mode is the default one.

Hi, this is a bit old however the problem is STILL not solved. It has been getting on my nerves for a while and if there were decent free Windows FTP clients I would have given up on WinSCP a long time ago. Anyway, my rants aside, here is a work around that you might find useful. If you notice, the error message usually suggests that you try passive mode due to inability to open some port. Now there might be any reasons why a port cannot be opened and WinSCP cannot really change that. Nonetheless the software should be able to automatically switch to a passive connection which it currently most definitely does not do.

You have to tick the passive connection box. The way you do this is tick the Advanced options box. Then under Connection tick the passive one. I also selected IPv4 as the internet protocol (might not work in your case) and under Environment > FTP ticked the Force IP ... option. I'd suggest you save all that as a session and reuse the setting next time. If you are editing a saved session make sure that you save.

Hope this helps!

@Lauri: Are you using PASSIVE (PASV) connection? If so, you'll need to configure your client accordingly and ensure the proper PASV ports are open on your firewall if you are accessing your FTP server through one. FTP server admin, if other than you, will know the PASSIVE port range.

@Lauri: You cannot fix it. But the problem is tracked already, so it will be resolved eventually.

You haven't posted full log file, so I cannot tell for sure. But from the IP address I suspect this issue is what you are facing.

Please post a full log file showing failure with passive mode.

I'm not sure what you wanted me to see in the documentation. I've uninstalled and re-installed, checked and double checked my settings, host name, passwords, etc., tried both passive and active, and still cannot get through to the server. Here's the error message I'm getting now:

Could not retrieve directory listing
Can't open data connection.

It says that it is connected but each time it tries to retrieve the directory it fails. I know that other people are getting through to this server with WinSCP – what is going wrong for me?
Please HELP!

Please read documentation on Timeout detected message.
If that does not help, come back.

I just downloaded WinSCP. I've tried and tried to get it to connect to the server, but it doesn't work. I've been through the FAQ and all but couldn't find anything to help. This is the error message that I get:

Timeout detected.
Could not retrieve directory listing
Opening ASCII mode data connection for /bin/ls.
Error listing directory '/'.

Can you help me?
