Validation fails. Error code: timeout-or-duplicate

[cyberdevteam]

Everything was working fine until last week when every validation fails with the error code "timeout-or-duplicate". After adding some debug lines this is what I get:

[2017-07-06 14:58:48] local.DEBUG: [Recaptcha] Request: https://www.google.com/recaptcha/api/siteverify?secret=....
[2017-07-06 14:58:48] local.DEBUG: [Recaptcha] Response: {
  "success": true,
  "challenge_ts": "2017-07-06T18:58:05Z",
  "hostname": "vagrant.local"
}
[2017-07-06 14:58:49] local.DEBUG: [Recaptcha] Request: https://www.google.com/recaptcha/api/siteverify?secret=...
[2017-07-06 14:58:49] local.DEBUG: [Recaptcha] Response: {
  "success": false,
  "challenge_ts": "2017-07-06T18:58:05Z",
  "hostname": "vagrant.local",
  "error-codes": [
    "timeout-or-duplicate"
  ]
}

It seems that in every validation two calls are made, so Google response is true for the first and false for the second since is considered duplicate.

I'm using a request validation object and my rules are set like this:

/**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        $rules = [
            'motive' => 'required',
            'name' => 'required|min:3|max:250',
            'last_name' => 'required|min:3|max:250',
            'address' => 'required|min:3|max:250',
            'address_number' => 'required|integer|min:0',
            'address_info' => 'max:250',
            'email' => 'required|email|max:250',
            'event_address' => 'required|min:3|max:250',
            'event_address_number' => 'required|integer|min:0',
            'event_address_info' => 'max:250',
            'message' => 'required|min:3|max:1000',
            'g-recaptcha-response'  => 'required|recaptcha',
        ];
        return $rules;
    }

Any ideas how to prevent duplicate calls to google recaptcha API?

Having this same issue (validator running twice), but with my own Recaptcha validation code. Could this be an obscure Laravel issue?

[singhservesh]

@TWilson023 Can you explain issue in detail. It seems you are validating same user captcha response twice. What api are you using for validating captcha response ? Can you paste you code snippet which does validation ?

This might require resetting your captcha, to prevent duplicates. Try calling the grecaptcha.reset();
