✅ Failed to bind to address http://127.0.0.1:5196: address already in use

Hi firends,
I'm working on a project using Microservices, I use

RabbitMQ

RabbitMQ

as the message broker, and the

MassTransit

MassTransit

as the abstraction layer over the

RabbitMQ

RabbitMQ

.
I have a service called AuthService which uses the

RabbitMQ

RabbitMQ

, another service called

ExpenseService.API

ExpenseService.API

also uses the same

RabbitMQ

RabbitMQ

appsettings.json

appsettings.json

of both services/projects have the same follwing

RabbitMQ

RabbitMQ

options

"RabbitMQ": {
    "Settings": {
      "HostName": "rabbitmq://localhost",
      "UserName": "guest",
      "Password": "guest"
    },

    "Endpoints": {
      "AuthService": {
        "UserCreatedEventQueue": "AuthService-UserCreatedEventQueue"
      }
    }
  }

"RabbitMQ": {
    "Settings": {
      "HostName": "rabbitmq://localhost",
      "UserName": "guest",

    },

    "Endpoints": {
      "AuthService": {
        "UserCreatedEventQueue": "AuthService-UserCreatedEventQueue"
      }
    }
  }

in the

program.cs

program.cs

ExpenseService.API

ExpenseService.API

I have this part which configure the project to be a consumer/subscriber :

var authServiceRabbitMqEndPointsOptions = builder.Configuration.GetSection("RabbitMQ:EndPoints:AuthService").Get<AuthServiceRabbitMqEndpointsOptions>();
var authServiceRabbitMqEndPoints = authServiceRabbitMqEndPointsOptions;


builder.Services.AddMassTransit( busConfigurator => 
{
    busConfigurator.UsingRabbitMq((context, cfg) => 
    {
        cfg.ReceiveEndpoint(authServiceRabbitMqEndPoints.UserCreatedEventQueue, ep => ep.Consumer<UserCreatedMessageConsumer>());
    });
});

var authServiceRabbitMqEndPointsOptions = builder.Configuration.GetSection("RabbitMQ:EndPoints:AuthService").Get<AuthServiceRabbitMqEndpointsOptions>();
var authServiceRabbitMqEndPoints = authServiceRabbitMqEndPointsOptions;


builder.Services.AddMassTransit( busConfigurator => 
{
    busConfigurator.UsingRabbitMq((context, cfg) => 
    {
        cfg.ReceiveEndpoint(authServiceRabbitMqEndPoints.UserCreatedEventQueue, ep => ep.Consumer<UserCreatedMessageConsumer>());
    });
});

When I start

AuthService

AuthService

then

ExpenseService

ExpenseService

I get this exception :

Exception has occurred: CLR/System.IO.IOException
An unhandled exception of type 'System.IO.IOException' occurred in System.Private.CoreLib.dll: 'Failed to bind to address http://127.0.0.1:5196: address already in use.'
Inner exceptions found, see $exception in variables window for more details.
Innermost exception System.Net.Sockets.SocketException : Only one usage of each socket address (protocol/network address/port) is normally permitted.

Please I hope someone to provide a help here and massive thanks in advance
