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

Log Type: APPLICATION

Log Level: ERROR

## Description

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

* 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.

### Possible solutions

* 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`.
