POST request in Laravel 401 UNAUTHORIZED - laravel

Question

I have following error when try to send mail from Laravel 7 using mailgun driver.
Client error: `POST https://api.eu.mailgun.net/v3/mail.firstdomain.com/messages.mime` resulted in a `401 UNAUTHORIZED` response: Forbidden
C:\laragon\www\lara7\vendor\guzzlehttp\guzzle\src\Exception\RequestException.php#113
GuzzleHttp\Exception\ClientException
It was working before and I don't remember at which point error appeared.
Before I got one problem with mailgun. It was like I see in debugbar that mail is sent, but then it is not delivered to recepient.
And problem was that FROM field was empty and in mailgun account those messages were located in BOUNCE list without movement.
Now there is nothing blocked at mailgun side. I think they are blocked somewhere inside Laravel.
Here is my code
routes\web.php
Route::post('/mymail', 'MainController#mymail')->name('mymail');
.env
MAIL_MAILER=mailgun
MAIL_FROM_ADDRESS=noreply#firstdomain.com
MAIL_FROM_NAME="robot name"
MAIL_TO_ADDRESS=user#seconddomain.com
MAIL_TO_NAME="TO name"
MAIL_REPLY_TO_ADDRESS=abc#seconddomain.com
MAIL_REPLY_TO_NAME="my name"
MAILGUN_DOMAIN=mail.firstdomain.com
MAILGUN_SECRET=mysecret
MAILGUN_ENDPOINT=api.eu.mailgun.net
**config\mail.php*
'default' => env('MAIL_MAILER', 'mailgun'),

}

Answer 1

As per Mailgun documentation: https://documentation.mailgun.com/en/latest/api-intro.html#errors
401 Unauthorized - No valid API key provided
Make sure that you are using valid API key - or sending to registered email addresses if you are using Sandbox.

Answer 2

Try after whitelisting your servers IP:
Mailgun Dashboard > Settings > API Keys > API Security IP Whitelist
Once added, it may take a few minutes to become active, after which you should be able to send emails from your laravel app
