Problem with Spotty Spotify Authorization

> [21-12-23 11:13:07.8037] Plugins::Spotty::Settings::Auth::handler (64) Trying to authenticate using: "/var/lib/squeezeboxserver/cache/InstalledPlugins/Plugins/Spotty/Bin/i386-linux/spotty-x86_64" -c "/var/lib/squeezeboxserver/cache/spotty/__AUTHENTICATE__" -n "Spotify Authorization (Helms Media)" -u "fex6cwppj79oeagy8c1csphk3" -p "********" -a --disable-discovery

Can you try to run this command in a terminal and let me know about the
outcome?
