Question

我们已经在一个Windows服务应用程序上实现了RabbitMQ，该应用程序将与我们的生产环境中托管的服务器进行通信。

我们已在客户端网络上将我们的域列入白名单，并在我们的服务器上打开了端口5672。

此配置在其中一个客户端网络上正常工作。

但是在另一个客户端网络上，它会导致以下错误

很明显，RabbitMQ客户端（Windows服务）无法与我们的prod环境中托管的RabbitMQ服务器建立连接，但不确定导致此问题的原因和原因。

我们还需要确保在客户端网络中为IN和OUT绑定连接打开端口5672吗？

我们使用域名（test.server.com）作为RabbiMQ主机名来建立连接。

由于错误说它无法解析DNS，是否需要提供IP地址而不是域名？

无法从客户端网络
