Gateway

Bug Fixes

Release date: October 21, 2024

Client SDK

Bug Fixes
  • [LS1-2358] [Web] Resolved intermittent WebSocket signaling disconnections on macOS Sequoia (15.0, 15.0.1) that caused unexpected client unregistration. Implemented client-side keep-alive mechanisms and increased Gateway signaling timeout to 15 seconds to prevent "604::Client does not exist" errors and unwanted connection drops. Applications using affected macOS versions should upgrade to ensure stable WebSocket connectivity.
