TLS connections do not work on native targets

[tobyloki]

I have gotten the grpc request to work on Android, but on iOS, I am getting the below error at runtime: UNKNOWN. The request doesn't reach my server (even if I put a fake server domain, it gives same error). How can I get it working on iOS?

private fun getStub(): AuthStub {
        val channel = Channel.Builder
            .forAddress(_GRPC_HOST, 443)
            .build()
        val stub = AuthStub(channel)
        return stub
    }

override suspend fun validateAccessCode(accessCode: String) = withContext(Utility.CoroutineContextProvider.io) {
        val request = Empty()

        val authMetadata = getAuthMetadata(accessCode)

        try {
            authGrpc.ValidateAccessCode(request, authMetadata)
        } catch (e: Exception) {
            throw GrpcUtility.handleException(e, "authGrpc.ValidateAccessCode")
        }

        return@withContext
    }

[TimOrtel]

Could it be that your iOS application is missing an internet permission or that your iOS device is offline? Based on this error message: kotlin.Exception: Network connection failed. Please check your internet connection and try again.

[tobyloki]

It is not because of a network problem. That was actually a log message that I made up when printing UNKNOWN status. Could it be because I am missing the required pods? I see that in https://github.com/TimOrtel/GRPC-Kotlin-Multiplatform/tree/main/example#ios-example, I am supposed to run pod install, but there is no Podfile.

[TimOrtel]

It's not because of pods as this library does not use pods anymore as of version 1.0.0. The readme is outdated.

Are you sure you are not receiving anything on the server? In any case, I suggest you try to send the same network request with an empty metadata object and check if the server now receives the request. Just to rule out that it is not a problem with the metadata implementation of the library.

[tobyloki]

I tried without the metadata to be empty authGrpc.ValidateAccessCode(request), but it still gives the same UNKNOWN status.

[tobyloki]

I also tried with the example app and got the below log.

Here is my modified hello.proto

syntax = "proto3";

import "google/protobuf/empty.proto";

package auth;

option java_multiple_files = true;

service Auth {
  rpc ValidateAccessCode (google.protobuf.Empty) returns (google.protobuf.Empty);
}

[TimOrtel]

I will try to reproduce the error using your proto file.

In the meantime, can you try what happens when you build the example app and example server without modifications? Do you get the same error?

[tobyloki]

I used the default example hello.proto, but still get the same error. I should also mention that I've been calling the host on port 443 and removed the .usePlaintext() call.

[TimOrtel]

I built a local version of the example app with your provided proto file and I could not observe the error you are getting.

To narrow down the problem, could you please try the following:

1. Try with usePlaintext and a different port.
2. Clone this repository, build the example app and start the example server and verify if the error also occurs in this setup.

[tobyloki]

I usePlaintext and a different port, and now the example works. So how do I get it working on a secure port?

[TimOrtel]

Thank you for the info. This could simply be a bug that needs to be fixed in this library. I will try to reproduce it tomorrow and provide a fix if necessary.

[TimOrtel]

I was able to reproduce the error. I will try to provide a fix and release a version 1.0.1.

[gregiOS]

Waiting for this fix as well
