Can't connect about bitfinex-v2-wss-api-java HOT 8 CLOSED

Hi,

The API of Bitfinex is sometimes unstable and the driver needs a few connection attempts until a connection is established. According to the exception, you get the HTTP error 400 (Response code was not 101: 400) back from Bitfinex. Please wait a few minutes and try it again.

Hello @jnidzwetzki,

Still does not work, but works with my custom websocket code sample.

from bitfinex-v2-wss-api-java.

Hi,

Up to now I have not been able to reproduce the problem. Could you post an example to reproduce the issue?

Best Regards

from bitfinex-v2-wss-api-java.

I have just used the example:

public static void main(String[] args) {
BitfinexApiBroker bitfinexApiBroker = new BitfinexApiBroker("xxx", "yyy");
try {
bitfinexApiBroker.connect();
} catch (APIException e) {
log.error("Could not connect to Bitfinex API", e);
}
}

and I get:

Hi,

I'm sorry, but I was unable to reproduce the problem. Your test code works fine for me.

• Which Java version do you use?
• If you have a static IP address, could you try to connect from a different IP?

Best Regards

Hello,

• I am using Java 8

• I tried from a different IP, it didn't change a thing. In the meantime, I have developped my own bitfinex WS implementation, but I would be happy to help if I can.

Hello,

Could you try to add the following class to your project and execute it? Is this class able to establish a connection or do you see an exception?

import java.net.URI;

import javax.websocket.ClientEndpoint;
import javax.websocket.CloseReason;
import javax.websocket.ContainerProvider;
import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.WebSocketContainer;

import com.google.common.base.Throwables;

@ClientEndpoint
public class WebsocketTest {
	
	public final static String BITFINEX_URI = "wss://api.bitfinex.com/ws/2";
	
	public static void main(String[] args) throws Exception {
		final WebsocketTest websocketTest = new WebsocketTest();
		websocketTest.connect();
	}
	
	private void connect() throws Exception {
		final WebSocketContainer container = ContainerProvider.getWebSocketContainer();
		final URI bitfinexURI = new URI(BITFINEX_URI);
		container.connectToServer(this, bitfinexURI);
		Thread.sleep(100000);
	}

	@OnOpen
	public void onOpen(final Session userSession) {
		System.out.println("Websocket is now open");
	}
	
	@OnClose
	public void onClose(final Session userSession, final CloseReason reason) {
		System.out.println("Closing websocket: " + reason);
	}

	@OnMessage
	public void onMessage(final String message) {
		System.out.println("Got message: " + message);
	}
	
	@OnError
	public void onError(final Session session, final Throwable t) {
		System.out.println("OnError called:" + Throwables.getStackTraceAsString(t));
	}
}
