Chat stopped: check the platform's card in Integrations. YouTube and Rumble chat only come in while you're live.
Sign-in expired: open the card's settings with the gear and choose Reauthenticate (Twitch, YouTube, and Kick).
Alert didn't show: check Next Up. With Auto off, alerts wait for you to fire them, and Pause queue in the menu bar or system tray holds them.
Send failed: check that the card shows Connected. On the free plan, Konduit sends to your one active platform.
If a connection doesn't come back after a network change, restart Konduit.
Still stuck: use Report a Bug in the app, or email support@konduit.gg with the platform, the time, and your Konduit version.
