RabbitMQ创建Channel时报Connection reset

Question

        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setPort(5672);
        connectionFactory.setUsername(username);
        connectionFactory.setPassword(password);
        connectionFactory.setHost("localhost");
        connectionFactory.setVirtualHost("/");
        var conn = connectionFactory.newConnection();
        var channel = conn.createChannel();
        conn.close();

这段代码会在channel建立的时候报Connection reset，用多种编程语言试过，请问可能有些什么原因，以下是RabbitMQ的日志

Answer 1

网络问题：检查网络连接是否正常，并确保能够连接到 RabbitMQ 服务器。您可以尝试通过 ping 命令或 telnet 命令来测试与服务器的连接。

防火墙配置：确保防火墙允许与 RabbitMQ 服务器的通信。如果您的服务器上有防火墙，您需要确保 RabbitMQ 的端口（默认情况下为5672）是开放的。

证书配置：如果您使用了 SSL/TLS 连接，可能会涉及到证书配置。确保您的证书配置正确，并且证书没有过期或被撤销。

RabbitMQ 服务器配置：检查 RabbitMQ 服务器的配置文件，确保它正确配置并且没有错误。特别注意检查监听地址、端口和身份验证等配置项。

并发连接限制：RabbitMQ 默认有一些并发连接限制。如果您的应用程序同时创建了大量的连接和通道，可能会达到服务器的限制。您可以尝试减少并发连接数量，或者调整 RabbitMQ 服务器的配置来提高并发连接的限制。
