Hello,
My plex webhook scrobbler always stop working every days. Each morning, need to delete it from Plex and re-add it to make it work and this since months.
Push notifications and webhooks are activated on my plex.
Is there something I missed in settings ?

Thank you in advance

Is Plex updating or restarting itself? This is the first time I’ve heard of an issue like this.
