bloomrpc | GUI Client for GRPC Services

I am trying to connect a Flutter app to gRPC server. It used to work fine in my older laptop, but now I always get this error when I try to make a request to an endpoint:

I'm novice in gRPC. My program is written with ‍‍nuxtjs and is a simple login page that receives the username and password and sends it to the server using gRPC. Everything is fine when I submit a request with BloomRPC. But when using the browser, the request is not sent to the server.

My auth class is as follow:

I'm struggling to get a gRPC client built with Xamarin.Forms to communicate with a gRPC server running on my localhost. The server can be reached without issue with BloomRPC, however I can't seem to get it to work properly from my client. The server is listening on http://localhost:5000 and https://localhost:5001.

I initially thought that perhaps it was because it's running on localhost that my client is struggling, so I also tried using a RemoteURL courtesy of Conveyor by Keyoti, which is set to http://192.168.1.64:45455 and https://192.168.1.64:45456, however I'm not quite sure how that works with my gRPC server as it is specifically listening on ports 5000 and 5001. Either way, trying to connect by either method results in an RPCException stating "failed to connect to all addresses".

I'm using the Grpc.Core library, and Grpc.Core.Xamarin (version 2.41.1) with the below code. I've also tried using version 1.20.1, but without success. The below code tries to connect to the authentication service which simply returns a GUID.

I realize that this a rather service specific subject, but I think that the reason for my problem is a general one, since I'm a novice in the gRPC arena.

I'm attempting to call a simple method PeerVersion in the Concordium blockchain gRPC API (https://github.com/Concordium/concordium-grpc-api) from a .NET Core 3.1 app, but I get what seems to be a rather general error in regard to SSL.

I can add that I have testet this call and others with BloomRPC (https://github.com/uw-labs/bloomrpc) and it works just fine.

You wont be able to call the API successfully without access to a Concordium node, but I recon that someone with better insight into gRPC than me, could maybe see what I'm doing wrong.

C# code

I've Docker Desktop Kubernetes cluster setup in my local machine and it is working fine. Now i'm trying to deploy .Net Core gRPC server and .Net core Console load generator to my cluster.

I'm using VisualStudio(2019)'s default template for gRPC application

Server:

proto file

I have a TypeScript server trying to read a JSON object using a Struct but it seems to be partially working only for objects containing a "fields" key which then expects an object as value. Nonetheless, a Struct should work with any JSON object.

Using BloomRPC I am trying the following message:

I have a server-side streaming RPC hosted on Google Cloud Run.

With the following proto definition:

I have a flask app that needs to make a request to a grpc server when a request is made to the flask endpoint.

I'm starting out on gRPC, my proto looks like:
