ArgumentException: No ip address could be resolved for IP

[tas...@trigonongroup.com]

Hello.

I'm using this sample https://github.com/MassTransit/Sample-RequestResponse

And i have written the client part using the .net core version of  masstransit which includes  "RabbitMQ.Client/5.0.1"

The same code (using the ip address) works fine on the .net version.

But on the .net core i get

ArgumentException: No ip address could be resolved for IP

I tried to add a fake hostname that points to the ip via hosts but althought i don't get the same error i get

time out errors.

Any ideas please?

ps:I'm trying to find out if i can use the .net core version for production.Any suggestions?

Hi,

I don't really know MassTransit but without seeing your code it is very difficult to see what may be wrong.

Have you tried making a connection using only the RabbitMQ client directly? 

Cheers

Hello.

You are right.

So this is the .net core code that can't connect https://pastebin.com/frkFSRbW

and this is the .net code https://github.com/MassTransit/Sample-RequestResponse/blob/master/src/RequestService/Program.cs

which accepts messages from the .net core and replied with the same message.

Using curl

curl -i -u foo:bar "http://foo:15672/api/queues"

 

returns correctly.

I don't know if this is related

https://github.com/rabbitmq/rabbitmq-dotnet-client/issues/260

but also i couldn't understand what is the solution.

Thanks!

ps:The same code https://github.com/MassTransit/Sample-RequestResponse/blob/master/src/Client/Program.cs

using .net framework works correctly.

I'm not sure what the rabbitmq:// scheme is - is it something MassTransit specific? - normally you would use amqp: or amqps:

None of that code use the .NET client directly so perhaps it would be better to raise this with the MassTransit folks?

Can you check that you can telnet into port 5672 (not 15672 which is the http api)?
