[QUERY] How to resolve javax.net.ssl.SSLException: handshake timed out

[rajadilipkolli]

Query/Question
Receiving handshake time out Exception when using azure-messaging-eventhubs-checkpointstore-blob to checkpoint the eventHub. How to resolve this?

Code is integrated with Spring Boot version 2.1.11 and it is deployed in OpenShift 3.11
Below is the error
{"timestamp":"2020-02-02T09:15:19,427+0000","project":"dummyservice","log_level":"WARN","thread":"reactor-http-epoll-2","class_name":"reactor.util.Loggers$Slf4JLogger","line_number":"299","message":"[id: 0xa0f8e1a6, L:/10.74.29.164:46426 - R:dummystorage.blob.core.windows.net/x.x.x.x:443] The connection observed an error","stack_trace":"javax.net.ssl.SSLException: handshake timed out\n\tat io.netty.handler.ssl.SslHandler$5.run(SslHandler.java:2011)\n\tat io.netty.util.concurrent.PromiseTask.runTask(PromiseTask.java:98)\n\tat io.netty.util.concurrent.ScheduledFutureTask.run(ScheduledFutureTask.java:150)\n\tat io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java:163)\n\tat io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:510)\n","status":"","duration_millis":"","application_tier":"","action":"","trace_id":""}

Why is this not a Bug or a feature Request?
I feel this is a Question because it is conveying as HandShake Exception instead of any other exception.

Setup (please complete the following information if applicable):

• OpenShift : 3.11
• Version of the Library used : 1.0.0-beta.4

Assigning to @srnagar and @conniey to investigate. Thanks for the report!

@rajadilipkolli - could you please let us know how you are creating the container client? It would be great if you could provide a reproducible code sample for us to investigate further.

We are using eph 3.0.2 and it is working as expected with the storage connection being made using sas, Now when I tried to connect using the latest 5.0.x we are receiving the above reported error. With the sample provided by Microsoft We face this issue.

Note:: we are behind corporate proxy and setting proxy using below code.

// set the ProxySelector API; which offers the flexibility to select Proxy Server based on the Target URI.

    ProxySelector systemDefaultSelector = ProxySelector.getDefault();
     ProxySelector.setDefault(new ProxySelector() {
       @Override
       public List<Proxy> select(URI uri) {
         if (uri != null && uri.getHost() != null && (uri.getHost()
             .equalsIgnoreCase(azureConnectionProperties.getNamespace()) || uri.getHost()
             .contains(azureConnectionProperties.getStorageUriHost()))) {
           LinkedList<Proxy> proxies = new LinkedList<>();
           proxies.add(getProxyAddress());
           return proxies;
         }

         // preserve system default selector for the rest
         return systemDefaultSelector.select(uri);
       }

       @Override
       public void connectFailed(URI uri, SocketAddress sa, IOException ioe) {
         // trace and follow up on why proxy server is down
         log.error(
             "Connection failed using proxy for uri :{} , socket address :{} and exception is :{}",
             uri, sa, ioe);
       }
     });

     log.debug("proxy set");
   }

We rewrote Event Hubs using the new API guidelines. Subsequently, the approach used in 3.0.2 may not be the same approach to use when configuring the HTTP client.

In your BlobContainerClientBuilder, you may have to set the httpClient with a proxy for the requests to be passed through there.

Hi @conniey , I have configured AsyncHttpClient, still facing the same issue.

[srnagar]

@rajadilipkolli Here's a sample for configuring your proxy:

ProxyOptions proxyOptions = new ProxyOptions(ProxyOptions.Type.HTTP,
  new InetSocketAddress(HOST_NAME, PORT));

HttpClient httpClient = new NettyAsyncHttpClientBuilder()
  .setProxy(proxyOptions)
  .build();

ContainerAsyncClient containerAsyncClient = new ContainerClientBuilder()
  .endpoint(endpoint)
  .connectionString(STORAGE_CONNECTION_STRING)
  .containerName(CONTAINER_NAME)
  .httpClient(httpClient)
  .buildAsyncClient(); 

If you are still facing issues, it would be great if you could provide a code sample of how you are creating the ContainerAsyncClient and the HttpClient that is provided to the ContainerClientBuilder to help us reproduce this error.

@rajadilipkolli were you able to get this to work?

[srnagar]

Closing this issue as there is no update. Please feel free to reopen if you are still having an issue using proxy.
