51131: Twilsock: Authentication failed
ERROR
This error occurs when Twilsock cannot authenticate the Access Token presented by a client SDK connection. Access Tokens are short-lived JWTs for Twilio client-side SDKs, and authentication failures are commonly caused by incorrect credentials, invalid token structure, or token timestamp issues.
- The token was generated with an incorrect or mismatched
Account SID,API Key SID, orAPI Secret. (help.twilio.com) - Test credentials were used to create the token. Access Tokens must use live credentials. (help.twilio.com)
- The token was created for a different account or subaccount than the Conversations Chat Service or Sync Service the client is trying to use. (help.twilio.com)
- The token did not include the correct product grant for the SDK you are using. Conversations requires a
ChatGrantwith your Conversation Service SID. Sync requires aSyncGrantwith your SyncserviceSid. - The client sent the token in the wrong format, such as a JSON object instead of the raw JWT string. (help.twilio.com)
- The token is outside its valid time window. Access Tokens have a maximum lifetime of 24 hours. (help.twilio.com)
- Regenerate the token on your server with the correct live
Account SID,API Key SID, andAPI Secretfrom the same Twilio account that owns the target service. (help.twilio.com) - Use a Twilio server-side helper library to create the token and grants instead of building the JWT manually. (help.twilio.com)
- For Conversations, add a
ChatGrantthat includes the correct Conversation Service SID. For Sync, add aSyncGrantwith the correctserviceSid. - Return the token to the client as a plain JWT string and initialize the SDK with that value. (help.twilio.com)
- Reissue tokens before they expire. If your Conversations client enters the
Deniedconnection state, fetch a new token and reconnect. - Review the Twilio Console Debugger or Workbench to inspect related errors and identify any more specific token validation failures.
