Unable to stream from FTP server

Platform

• VLC: 3.3.0 (404-409)
• iPad 2 : iOS 9.3.5
• iPhone 6s : iOS 14.8
• FTP Server: Filezilla (0.9.41 beta) from ApacheFriends XAMPP Version 5.6.28

Reproduction steps

1. Connect to FTP server
2. Browse the directory (notice that thumbnails doesn't show up even though it's enabled in the settings)
3. Play a video

Issue

It closes the player but stays in the app

Additional details

Downloading from the FTP and playing it locally works.

I also tested streaming on another player (nplayer) and it works so this is VLC-specific
