easywechat Failed to fetch key access_token

不管是原来的还是redis都报下面的错误。有没有大佬解决这样的问题？影响到了线上的项目了。用的基于thinkphp5.1的fastadmin框架。

1. easywechat 版本4.x
2. igbinary已安装

 $config = [
     'app_id' => $this->wechatAppid,
     'secret' => $this->wechatAppsecret,
 ];
 $app = Factory::officialAccount($config);
 $redis = \think\Cache::store('redis')->handler();
 $cache = new RedisAdapter($redis, $namespace = '', $defaultLifetime = 0);
 $app->rebind('cache', $cache);
 $res = $app->template_message->send($data);

总是报这些问题
