Endpoint.Start FirstChanceException

when we run endpoint.start we get several FirstChanceExceptions saying

System.ArgumentException: No ip address could be resolved for thehostname. RabbitMQ.Client.TcpClientAdapter.<ConnectAsync>d__2.MoveNext()
— Slutt på stakksporing fra forrige plassering der unntak ble iverksatt —

ved RabbitMQ.Client.Impl.SocketFrameHandler.ConnectOrFail(ITcpClient socket, AmqpTcpEndpoint endpoint, Int32 timeout) 

is this a problem With the configuration or can this exception be ignored ?

If all you’re seeing is a first-chance exception, then there is nothing to worry about. If you aren’t getting an actual unhandled exception, then that exception is being properly handled.

See First-Chance Exception for more information.
