The message "ignoring answer for old offer" in LiveKit occurs during WebRTC negotiation when an answer is received that does not correspond to the most recent offer that was sent. Specifically, if the received answer's

offerId

does not match the

latestOfferId

, LiveKit will log this warning and ignore the outdated answer. This helps prevent negotiation issues caused by out-of-sequence signaling messages. Example (from code):

if (sd.type === 'answer' && this.latestOfferId > 0 && offerId > 0 && offerId !== this.latestOfferId) {
  this.log.warn('ignoring answer for old offer'...)
  return false;
}

At this time, I do not have information on the specific message "negotiation disconnected" in the available documentation. Sources: src/api/SignalClient.ts
