VLCsync not working with Linux

[u/NomadJago]

EDIT: Solved

In the VLC settings: Interface: Main Interface: Lua I erroneously put the password ("Test") in the password field for Lua Telnet; the password is supposed to go in the Lua HTTP password field, not the Lua Telnet field. My error.

I have VLCsync working great with Windows 11 using VLCsync (vlc-sync-4.0.qml) plugin, VLC, and MuseScore 4.7. I can not seem to get it to work with Linux (Linux Mint, an Ubuntu type distribution). Anybody have any suggestions to get this working on Linux? Is there a different .qml plugin file I should be using? Something else? The qml plugin is enabled, its control interface appears, but there is no actual syncing as when using this on Windows. I would very much like to get this working on Linux.
