Not able to connect RabbitMQ server using TLS 1.2 from RMQ client , getting exception

[somes bhowmick]

Hi All, 

I am getting exception to connect RMQ server using TLS 1.2 connection string . 

I am getting the following exception :

RabbitMQ.Client.Exceptions.BrokerUnreachableException: None of the specified endpoints were reachable ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

   at RabbitMQ.Client.EndpointResolverExtensions.SelectOne[T](IEndpointResolver resolver, Func`2 selector)

   at RabbitMQ.Client.Framing.Impl.AutorecoveringConnection.Init(IEndpointResolver endpoints)

   at RabbitMQ.Client.ConnectionFactory.CreateConnection(IEndpointResolver endpointResolver, String clientProvidedName)

   --- End of inner exception stack trace ---

   at RabbitMQ.Client.ConnectionFactory.CreateConnection(IEndpointResolver endpointResolver, String clientProvidedName)

   at NServiceBus.Transport.RabbitMQ.ConnectionFactory.CreateConnection(String connectionName) 

We are using NserviceBus 6 and Rabbit MQ client version = 5.0.1

Server : windows 2012 R2

Any  remedy, Need urgent help. I have stuck there

Hello,

This is the important error:

The remote certificate is invalid according to the validation procedure.

By default, the RabbitMQ .NET client doesn't validate server certificates (https://github.com/rabbitmq/rabbitmq-dotnet-client/issues/339)

How are you configuring the .NET client to validate the server certificate? Could you please share your connection code?

Thanks -
Luke
