mprisence cannot connect to Discord IPC although everything is properly configured

[EpocDotFr]

Hello,

mprisence cannot connect to Discord IPC, logs show: Could not connect to Discord IPC socket. Presence updates will be disabled until connection succeeds.. I double-checked everything was properly configured, including:

• Discord Snap is in use (NOT the Flatpak release)

  • Everything is enabled in activity privacy settings

• My player is compatible:

   $ mprisence players list
   
   MPRIS players: 1 (1 playing, 0 paused, 0 excluded)
   ────────────────────────────────────────────────────────
   ▶ Rhythmbox                        Feel The Beatz — Techno Mix Sessi... [playing]
  

• Service is running:

   $ systemctl --user status mprisence
   ● mprisence.service - Discord Rich Presence for MPRIS media players
        Loaded: loaded (/usr/lib/systemd/user/mprisence.service; enabled; preset: enabled)

  Also I restarted Discord and the service several times.
