I have an FTP Share set up on the USB drive attached to my ZenWifi AX mesh router. Username and password must be provided, there are no anonymous logins and no WAN access.
I have no trouble ftp-ing via FileZilla from my desktop computers. Until a few days ago, I likewise had no trouble getting to it from the AndFTP app on my Android phone.
Abruptly though, the latter now fails (and I'm unable to identify what triggered this).
I've attempted to log in with FTP apps AndFTP and PowerFTP--which was installed to determine if this was an AndFTP--specific problem. It was not. Connection is refused to both apps and this message is displayed:
530 Non-anonymous sessions must use encryption
On the router administration's "FTP Share" page there is no mention of encryption, and I don't know where else I would look for that where it might affect FTP logins.
I would appreciate any advice.
