FTP Errors

[digitaldoughnut]

So I've just setup FTP access with explicit TLS on my WD MyCloudEX2Ultra. I am able to access it with FileZilla on LAN from my PC however I am unable to get any external access (yes I have port forwarded on the router). I used this site https://ftptest.net

to check external access and I get the following error:

    Error: Carriage return without line feed received

    The replies sent by your server are violating the FTP specifications.

    You have to upgrade to a proper server.

 

not sure how to fix this, there doesn't seem to be much on google.

Thanks

To be fair, FTP over TLS is a pretty odd choice.  Most people go for SCP or SFTP.

Your ISP may also be blocking the port.

It doesn’t seem like my NAS supports either of those options, thanks though!

I’m using virgin media - according to their list of Blocked ports there doesn’t seem to be any conflicts.

Wow, nice job WD, it seems SFTP and SCP is indeed not worth the risk as they only allow it for the root user because WD clearly haven't a clue what they are doing.

So back to FTP over TLS, did you forward both port 990(TCP/UDP) for control and port 989(TCP/UDP) for data on your router to the NAS?  There's also some mention of passive ports at https://community.wd.com/t/filezilla-ftp-over-tls/98598
