OS compatibility:
YPlayBoombox has been tested to work with Windows and Linux via Proton.

If downloading fails, make sure:

• Your firewall allows Lethal Company through.
• The server host is running the mod and you have the latest/same version of the mod as the server host.
• The YouTube URL ID fits in the chat box character limit, you may need to trim the https:// to fit in the link. Alternatively, you can right click a video and click "Copy video URL" which should give you a shorter link.

If that doesn't work then the plugin is probably bugging out or there is another mod that conflicts causing it to not work. You can contact me here if you find an incompatibility:
