Anyone else had FTP problems using Hone Internet?

I really appreciate the trouble you are going to to try to help me Jayke. It seems I am just a click away from finding a solution, but which click?!

I went to proxy settings because that’s where I found the option to turn passive mode on or off.

I see no “more options” at the bottom of the open connection window—I am guessing you are using the Windows version of Cyberduck, whereas I am on MacOS. (With its firewall turned off.)

I understand what you say about FTP being old technology lacking in security. However, when I took over the club website from my predecessor, he was using FTP so I did the same. There is no financial transaction or sensitive information on the website.

ACTUALIZACIÓN

I installed Forklift,  turned passive mode off, and connected to my website without problem. This is not the I  app I want to use, but this confirms Jayke's advice, and confirms there is nothing wrong with my laptop or my target website.

IThe issue of correctly configuring Cyberduck to work in non-passive mode remains, however. I  attach a screenshot of what I see when I open a connection on Cyberduck-no "more options" drop-down.

Here's the heart of the T-Mobile Home Internet FTP problem.  T-Mobile Home Internet ISP is IPV6 and my Cox Cable ISP is IPV4.  The older PASV FTP command (the default for at least my CuteFTP program) works perfectly on Cox Cable ISP but won't work on T-Mobile Home Internet IPV6. What did work is changing Data connection type in my FTP program from "Use global settings" to "Use EPSV"

"So, what's the difference now between EPSV and PASV? Or Extended Passive Mode and Passive Mode? The main difference is that EPSV and Extended Passive Mode are primarily designed to accommodate both IPV4 and IPV6 addresses, while the older PASV command and Passive Mode could only support IPV4."

This appears to be happening with my setup as well.  Here's my story:

I am running a Linux webserver on my local network. I used to upload to a webservice that I run to post data. Since I switched my router which was on Cox to the T-Mobile gateway the service failed.  When connecting via ftp (ftp -v -n satwatcher.us) I was getting this error:

220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
220-You are user number 14 of 150 allowed.
220-Local time is now 13:32. Server port: 21.
220-IPv6 connections are also welcome on this server.
220 You will be disconnected after 15 minutes of inactivity.

200 PORT command successful
425 Could not open data connection to port 48232: Connection timed out
221-Goodbye. You uploaded 0 and downloaded 0 kbytes.

I then tried switching to forced passive mode (adding the -p switch), “ftp -p -v -n satwatcher.us” as I saw this mentioned in another post and got this error:

220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
220-You are user number 15 of 150 allowed.

221-Goodbye. You uploaded 0 and downloaded 0 kbytes.

The syslog errors I’m getting look like this:

Apr  5 00:07:17 WeewxWeatherServer weewx[6678] DEBUG weeutil.ftpupload: Connected to ftp.satwatcher.us
Apr  5 00:07:17 WeewxWeatherServer weewx[6678] DEBUG weeutil.ftpupload: 0 ./dayradiation.png de3f1218ef30538449b2abc9ef9307dd622c82d61c61bd3a398a5b394a908201

Does anyone have any ideas of what I should try?

¡Gracias!

I had FTP failures with NCH Classic FTP.

Switched to Filezilla and works well.

Black gateway.

Thanks to jayke for his advice. I've been really frustrated with this problem. I maintain 3 sites, 2 with one provider and a 3d with another. I had no problem with FileZilla client and these sites with phone company DSL. Switched to TM Home Internet and problems began with the 2 sites but not the other. I would connect, but it was really slow trying to get into directories and would eventually time out with something like "4125 Users connected--too many." I communicated with my ISP and he had no trouble FTPing to the sites. Finally, I went to the library and used their WiFi and everything worked great. So, it had to be the TM gateway. But I can't go to the library whenever I need to maintain a site.

Following jayke's advice just now I tried FileZilla on both sites I maintain and in the Site Manager dialog box's Transfer Settings tab changed "Transfer Mode" from "Default" to "Active" and everything seems to be working. I can get into directories quickly and upload files.  

I wish TM had a better way to disseminate information like this. Actually, I wish they would FIX THE GATEWAY so it wouldn't be an issue going forward.

Thanks again, jayke.

Same problem trying to FTP to my web site was not working until I used SFTP. My web site provider only uses SFTP. Everything was  OK after that.

I'm having the same PASV issue with FTP not working through the KVD21.  The security system notifications uses this making this sort of a no-go unless I can find some sort of workaround.  

I have been using T-Mobile 5G internet for 10 days now and haven't been able to use FTP either generic, filezilla nor WinSCP. I use ftp at least twice a month and need this corrected or I will need to return to my slow DSL line with CenturyLink.
