php - Laravel 5.1 GuzzleHttp Client error: 404 when using mailgun -

i'm using mailgun service when sending mail laravel. however, i've set today , it's stopped working. have entered correct info in .env, config/services.php , config/mail.php. i'm still getting below error:

clientexception in middleware.php line 69:  client error: 404 

it looks domain not getting passed through somehow, though in config/services.php file have:

'mailgun' => [     'domain' => env('mydomain.com'),     'secret' => env('<my-mailgun-key>'), ], 

i have hidden above credentials safety, in real application proper values.

please help.

i hade same problem , solved removing env() call. thats because env return value of env variable in first argument (not value of argument) , otherwise return second argument.

so:

'mailgun' => [     'domain' => 'mydomain.com',     'secret' => '<my-mailgun-key>', ], 

try that.
