我想连接到webSocket，但出现了一个错误。如何解决这个问题？或者可能是服务器端的错误？
implementation 'com.squareup.okhttp3:okhttp:3.9.1'
Code:
final Request request = new Request.Builder()
.get()
.url("http://develop.by:8000")
.build();
OkHttpClient okHttpClient = new OkHttpClient.Builder()
.readTimeout(30, TimeUnit.SECONDS)
.writeTimeout(30, TimeUnit.SECONDS)
.build();
WebSocket webSocket = okHttpClient.newWebSocket(request, new WebSocketListener() {...}
Error:
java.io.IOException: unexpected end of stream on Connection{develop.by:8000, proxy=DIRECT@ hostAddress=develop.by/195.***.***.**:8000 cipherSuite=none protocol=http/1.1}
