363Most of the silence problems in this section span a whole workspace or channel and come down to configuration. When a single thread goes quiet and Claude answers everywhere else, the cause is a stuck session rather than a setting; see [Claude went silent in one thread, but responds elsewhere](#claude-went-silent-in-one-thread-but-responds-elsewhere).
363Most of the silence problems in this section span a whole workspace or channel and come down to configuration. If Claude stays silent in one thread but answers everywhere else, a setting isn't the cause. Either Claude's session for that thread is stuck, or the thread is muted. See [Claude went silent in one thread, but responds elsewhere](#claude-went-silent-in-one-thread-but-responds-elsewhere).

373The session behind that thread is stuck: it hasn't replied and hasn't posted an error. Because Claude responds everywhere else, the problem is confined to that one session, and none of the configuration fixes in the entries below apply.
373First check the thread for a notice from Claude that begins `:mute: Claude is muted in this thread`. If that notice is there, the thread is muted and the session isn't stuck. A 👎 reaction on one of Claude's replies mutes the thread and posts that notice. If Claude's session for the thread was partway through a reply, the reaction also stops that reply.
374
375To bring Claude back to a muted thread, send `@Claude !unmute` in the thread or @-mention Claude there, as [Thumbs-down reactions and muting](/docs/claude-tag/users/commands#thumbs-down-reactions-and-muting) describes.
376
377Without that notice, the session behind that thread is stuck: it hasn't replied and hasn't posted an error. Because Claude responds everywhere else, the problem is confined to that one session, and none of the configuration fixes in the entries below apply.
