[I] TLS negotiation failed when trying to accept new connection [dubbo]
lizf2014 opened a new issue, #13707:
URL: https://github.com/apache/dubbo/issues/13707
服务启动后，一直报以下错误，1s 出现一次，不影响接口调用，大家有人遇到过吗？
### Environment

@AlbumenJ 不太好复现，目前只有部分服务会出现这个 error，其他服务是正常的，配置和代码是一致的。
这个场景下，如果我改为使用 triple 协议，又会一直报下边这个错，也是 1s 一次：

@AlbumenJ 经过 debug 后，是下图中代码会抛出 Connection reset：

Add a breakpoint and get the config of remote address.

这个问题我遇到了，我们的情况是这样的：
1. 我们之前由于网络原因，使用了直连方式调用，后面因为负载原因，使用了阿里云的负载均衡（SLB）；
2. SLB有个存活检测，导致一秒钟调用一次20880接口，dubbo2.x的时候没有报错，dubbo升级到3.x的时候，这个就会报，原因应该是数据协议不兼容导致的
3. 解决方法：使用正常的注册中心调度即可，也可以关闭存活检测、或者存活检测22222端口，甚至可以单独开发一个接口专门用于存活检测。
