Ftp client ubuntu why not save files to server?

Question

FTP

Tell me what could be the problem. Any ftp client, including via Nautilus, connects to the server, but when trying to save the file to the server, an error occurs

Unable to save /run/user/1000/gvfs/ftp:host=95.85.30.201/public_html/index.php
Error: Ошибка ввода/вывода

Via filezilla- Unable to start transfer.
Ubuntu 15.04
Internet through a router from dom.ru.
From win there is no problem.
Tell me what could be the problem? At least in which direction to dig?
