### Environment

* Dubbo version: 2.7.12
* Operating System version: Linux 3.10.0-1160.11.1.el7.x86_64
* Java version: 1.8

### Steps to reproduce this issue

1. consumer 注解配置@DubboReference (cluster = "broadcast2")，使用广播模式调用provider
2. provider共四台机器
3. consumer调用provider，偶发以下"Invalid token"的报错，频率大概在1/100，并且报错时是4台provider机器同时报错。

Pls. provide [GitHub address] to reproduce this issue.

### Expected Behavior
广播模式正常调用


### Actual Behavior
广播模式下调用，偶发"Invalid token"报错，频率大概在1/100
