Fix AMQPConnectionError

✅ Solution

AMQPConnectionError usually arises from incorrect connection parameters (host, port, username, password) or the AMQP service being unavailable. Verify your AMQP_URL environment variable or connection string is correct and that the RabbitMQ service is running and accessible from where the opentelemetry-python application is deployed. Additionally, ensure any firewall rules allow communication on the AMQP port (typically 5672 or 5671 for TLS).
