60550: Auto Channel Failed: No channels selected due to validation errors. Check console.

Twilio Verify DocumentationVerify

Description

description page anchor

This error occurs when you start a verification with channel=auto and Verify cannot select a valid delivery path because the available channels fail validation. Automatic Channel Selection attempts Silent Network Auth first and uses SMS as a fallback when needed.

Possible causes

possible-causes page anchor
  • One or more delivery channels required for the request are disabled on your Verify Service.
  • Your account or Verify Service does not have access to a required feature for Automatic Channel Selection or Silent Network Auth. Automatic Channel Selection is a pilot feature and Silent Network Auth requires upfront Verify Service configuration.
  • The request uses channel=auto, but Verify cannot validate a usable path through Silent Network Auth or SMS for that verification attempt.
  • Open the Console Debugger and review the related debugger message to identify the specific validation error for the failed verification attempt.
  • In your Verify Service settings, enable the delivery channels your flow depends on. If you use channel=auto, make sure SMS is available as the fallback channel.
  • Confirm that your account has access to Automatic Channel Selection and that your Verify Service is configured for Silent Network Auth before sending requests with channel=auto.
  • Include device_ip when you use channel=auto so Verify can assess whether Silent Network Auth can be used for the device before falling back to SMS.
  • If you do not need Automatic Channel Selection, retry the verification with a supported explicit channel such as sms, call, whatsapp, email, or sna.
