Error when connecting to VLC over FTP

I’ve tried to connect to My Cloud EX2 Ultra using VLC over FTP on iOS and from Desktop version, but get error. On iOS I get an error that says, “SERVER CONNECTION FAILED Please check your server address and credentials.” On Desktop version, I see an error that says, “553 User not allow” after trying to retrieve file/video. I have been able to connect and retrieve files using a different FTP client. Any ideas on what might not allow it to work? I used to be able to connect with an older model from WD (My Book World Edition II). Thanks!

See the dedicated EX2 Series subforum where users more familar with that device may be able to assist.

Thanks, I’ll try there.
