UndeliverableException unhandled

[jurepetrovic]

Hello Gentlemen,

I'm getting

Stack Trace: io.reactivex.exceptions.UndeliverableException: java.net.UnknownHostException: ws.pusherapp.com

due to connection problems.
Where could I override onError() to catch this?
And where does it get thrown?
I can catch it only grom uncaught Exception handler in main class...

Is there any option I could use RxJavaPlugin.setErrorHandler() ?
This way I could set my own handler for this kind of errors..?

I'm looking a this page:

https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0#error-handling

It seems that unpredictable network errors (like sudden connection loss) need to be handled in exta global handler, that is part of RxJava package. Has anyone worked on that?

RxJavaPlugins.setErrorHandler(e -> {
    if (e instanceof UndeliverableException) {
        e = e.getCause();
    }
    if ((e instanceof IOException) || (e instanceof SocketException)) {
        // fine, irrelevant network problem or API that throws on cancellation
        return;
    }
    if (e instanceof InterruptedException) {
        // fine, some blocking code was interrupted by a dispose call
        return;
    }
    if ((e instanceof NullPointerException) || (e instanceof IllegalArgumentException)) {
        // that's likely a bug in the application
        Thread.currentThread().getUncaughtExceptionHandler()
            .handleException(Thread.currentThread(), e);
        return;
    }
    if (e instanceof IllegalStateException) {
        // that's a bug in RxJava or in a custom operator
        Thread.currentThread().getUncaughtExceptionHandler()
            .handleException(Thread.currentThread(), e);
        return;
    }
    Log.warning("Undeliverable exception received, not sure what to do", e);
});
