Bug Description

frps在一个网络不稳定的机器上，需要接收多个节点的数据到frpc所在的机器里，在网络不好的情况下，frpc经常会端口，在重连frps的时候，可能是因为frps下面的节点持续的传输数据到frps映射的端口上，导致端口一直无法释放，frpc就提示[XXX] start error: proxy [XXX] already exists

frpc Version

0.44.0

frps Version

0.51.3

System Architecture

linux/arm

Configurations

frps.ini
[common] bind_port = 3887 dashboard_port = 3888 log_file = /home/frp/frps.log token = 123123123

`[common]
server_addr = 123.123.123.123
server_port = 3887

好像 1.53.2 上面不发生了，还是没达到触发条件就不知道了。
