连接 PubNub 服务的频道时出现 PNTimeoutCategory 错误

如何解决连接 PubNub 服务的频道时出现 PNTimeoutCategory 错误

在尝试连接到 PubNub 服务时获取 PNTimeoutCategory。以下是我们收到的 PNStatus 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unsubscribe 频道并再次subscribe。

如何处理遇到的 PNTimeoutCategory 错误？
这是什么原因造成的？

使用的 PNConfig：

// 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
    }
});

我们目前使用的Pubnub lib是实现 'com.pubnub:pubnub-gson:4.19.0'
