I have this error on iOS client and I'm not sure how to fix it:

Error Domain=NSURLErrorDomain Code=-1011 "There was a bad response from the server." UserInfo={NSErrorFailingURLStringKey=<ws://test.com/rpc>, NSErrorFailingURLKey=<ws://test.com/rpc>, _NSURLLErrorWebSocketHandshakeFailureReasonKey=0, NSLocalizedDescription=There was a bad response from the server.}

This is my gradle build sourceSets:

...
sourceSets {
    androidMain.dependencies {
        implementation(libs.ktor.client.cio)
        implementation(libs.kotlinx.coroutines.android)
    }
    iosMain.dependencies {
        implementation(libs.ktor.client.darwin)
    }
    commonMain.dependencies {
        implementation(projects.shared)
        ...

        implementation(libs.ktor.client.core)
        implementation(libs.ktor.client.websockets)

        implementation(libs.kotlinx.coroutines.core)
        implementation(libs.kotlinx.rpc.krpc.client)
        implementation(libs.kotlinx.rpc.krpc.serialization.json)
        implementation(libs.kotlinx.rpc.krpc.ktor.client)
    }
    ...
}

Hey! I'm pretty sure because test.com/rpc doesn't exist as a krpc server

[Dumitru Preguza]

On Android it works
I just masked, the real domain is: ws://mafrend.com/rpc

[Dumitru Preguza]

@Alexander Sysoev if only it was so simple 🙂

[Dumitru Preguza]

There are similar unresolved cases:

[Alexander Sysoev]

Then it is a general question for #C0A974TJ9 about ws connections for your setup

[Dumitru Preguza]

I guess it could be because iOS client does not support websockes, okay thanks

[Alexander Sysoev]

No, we test on ios, it's not that

[Dumitru Preguza]

@Alexander Sysoev Both darwin client and cio ?
I will test later today with cio, if it works then I will open an issue for the darwin client

[Alexander Sysoev]

Yes, only cio, as we just use ktors ws plugin. If something doesn't work on darwin - it is their bug

[Dumitru Preguza]

update, CIO client impl. also fails and gives: TLS sessions are not supported on Native platform.
