So here I am travelling and using my laptop connected via my cellphone which acts as a hotspot. All works well: POP and SMTP email, browsing the web (obviously, since I am posting this) but I am unable to update any of my websites using FileZilla (latest version) via FTP over TLS, or SFTP.
Since I have sites on various hosting companies, and I am unable to FTP any of them, I asume this is a Vodafone problem or restriction. Can anyone confirm? And what is the workaround? I was able to use use File Manager in cPanel, but that's not a real substitute for FTP.
