Bug Description

通过STCP方式连接远程桌面,有几台服务器会报协议错误,start new visitor connection error: custom listener for [proxies-stcp-rdp-55F25A99-2B43-44A6-93E5-60223BF36941] doesn't exist
不知道这个serverName是不是有hash算法问题还是长度有限制

secretKey 不要贴出来，日志和配置无法看出问题，建议在本地环境用最小化的配置看是否能复现问题，如果可以，贴出完整的测试配置。

我也在怀疑serverName太长或前面某些部分有重叠的可能性,看了一下frp只用到了比较短的ID做为唯一标识

serverName 这个算法的确有问题换个serverName名字就可以连接上了,目前接了100个左右的客户端,serverName是用的工具生成的guid做为的serverName,检查过了也没有重复但就是连接不上真是怪了

@wb1t 尽量提供一个最简化的可复现的完整配置，否则很难测试。
