53000: Signaling connection error

Twilio Video DocumentationVideo

Description

description page anchor

Raised whenever a signaling connection error occurs that is not covered by a more specific error code.

Possible causes

possible-causes page anchor
  • The client could not establish a connection to Twilio's signaling server or the signaling path was lost.
  • Reconnection attempts were exhausted after a network disruption, resulting in a final disconnect with this error.
  • Corporate firewall or proxy is blocking secure WebSocket traffic required for signaling on TCP 443 to Twilio Video signaling hosts.
  • High latency to the chosen signaling region can slow or prevent establishing the signaling connection.
  • Retry connecting to the Room.
  • Ensure the user has a stable internet connection or try a different network.
  • Try connecting to another region or explicitly set the signaling region with the SDK region option, or rely on Global Low Latency.
  • Verify that firewalls allow outbound WSS to the appropriate regional signaling hostnames on port 443.
  • Ensure Access Tokens have sufficient TTL and are refreshed as needed so reconnections can authenticate successfully.
  • Handle reconnection states in your app and, if a 53000 disconnect occurs, prompt the user to rejoin the Room.
