We got an error form laravel 7, when rabbitMQ Connection in server. The same server Laravel 5.8 working fine, We use same login details for both 5.8 and 7. But 7 version only we that issue
ACCESS_REFUSED - Login was refused using the authentication mechanism AMQPLAIN. For details see the broker logfile.(0, 0) vendor/php-amqplib/php-amqplib/PhpAmqpLib/Connection/AbstractConnection.php:745
I Found the solution, This is an issue from .env file. Change name of login details from RABBITMQ_LOGIN to RABBITMQ_USER. it working fine.
