Wiem, że ten temat był poruszany na forach jakiś miliard razy. Ale próbowałem stosować najróżniejsze rady i dalej to samo. Zdjęcie ustawień FireWalla:

Status: Łączenie z ...
Status: Nieudana próba połączenia z "ETIMEDOUT - Przekroczony czas oczekiwania na połączenie".
Błąd: Nie można połączyć się z serwerem
Dane prawidłowe. Jak uruchamiam filemanager na cba to się udaje połączyć. Potrzebuję FileZillę albo innego klienta, żeby mieć dostęp do plików na innych serwerach.

The replies sent by your server are violating the FTP specifications.
You have to upgrade to a proper server.
