尝试连接到 PubNub 服务时获取 PNTimeoutCategory

得到PNTimeoutCategory尝试连接到 PubNub 服务时。以下是PNStatus我们收到的类别。

    PNErrorData(information=null, throwable=com.pubnub.api.PubNubException),
    error=true, statusCode=0, operation=PNHeartbeatOperation, tlsEnabled=false, 
    uuid=null, authKey=null, origin=null, 
    clientRequest=null, affectedChannels=[*************], 
    affectedChannelGroups=[],
    executedEndpoint=com.pubnub.api.endpoints.presence.Heartbeat@fe6406)

有时会发生这种情况，但随后我们必须取消订阅频道并重新订阅。

如何处理PNTimeoutCategory遇到错误？ 而这又是什么原因呢？

PNConfigs used:

    // configuration of KEY's
    PNConfiguration pnConfiguration = new PNConfiguration();
    pnConfiguration.setPublishKey(***);
    pnConfiguration.setSubscribeKey(***);
    pnConfiguration.setSecretKey(***);
    pnConfiguration.setAuthKey(***);
    
    // set secure i.e. set use of SSL
    pnConfiguration.setSecure(pnConfiguration.isSecure());
    
    pnConfiguration.setNonSubscribeRequestTimeout(NON_SUSCRIBE_REQUEST_TIMEOUT);
    
    // setting UUID as instance id
    String instanceId = Utility.getInstanceId();
    pnConfiguration.setUuid(instanceId);
    
    // Set reconnect policy: LINEAR means automatic reconnects
    // If a client gets disconnected from a channel, it can automatically attempt to reconnect
    // to that channel and retrieve any available messages that were missed during that period.
    pnConfiguration.setReconnectionPolicy(PNReconnectionPolicy.LINEAR);
    
    pubnub = new PubNub(pnConfiguration);
    
    // verify client connectivity to origin
    pubnub.time().async(new PNCallback<PNTimeResult>() {
        @Override
        public void onResponse(PNTimeResult result, PNStatus status) {
        //logs
        }
    });

我们当前使用的 Pubnub lib 是实现com.pubnub:pubnub-gson:4.19.0
