I was told that the problem is
1. blocking the ftp connection by the firewall (firewall) or antivirus of your computer.
2.problems on the side of intermediate nodes (between our server and your computer).
The first, I think, disappears ... But the second problem is solved by rebooting the router (off / on the router). But you have to do this all the time, several times a day, how to fix the problem?
connect via winscp

Answer 1

To your 2nd question, when there are problems with the connection, check if there are any losses on intermediate hosts to your FTP server. In the output 0% - no loss.

Answer 2

What FTP client are you using? Or from a browser open as ftp://login:[email protected]/ ?

Answer 3

Can't connect via ftp

Decide somehow already, how to connect something? FTP is FTP, WinScp is the scp windows client, part of ssh. There ports are completely different and everything is different :)

I tried FireZilla, Switching from passive to active., I tried to type ftp:// into the browser - an empty page.

Answer 5

Try telnetom to check availability of ports 20, 21 for ftp.
I also had such a nuance that I tried to connect via the winscp domain to ipv6, I decided to change the domain to the ipv4 server.
