frp设置https，昨天还好好的，今天突然提示router config conflict？

Question

业务需求，用frp做内网穿透，设置好了，ssl证书也部署好了，https也可以访问了。这样过了两周，今天突然不好用了，服务器上看看，服务都还在，进程没死，log提示如下：

2019/09/18 16:03:56 [I] [proxy.go:84] [c53886a12519bf6d] [web_https] get a new work connection: [139.227.136.47:6072]

搞了半天，没进展==

frps和frpc设置如下：

frps：

[common]
bind_port = 7000
dashboard_port = 7500
dashboard_user = frp_xiaocaigo
dashboard_pwd = xcg_lxysgnh_pwd
vhost_http_port = 80
vhost_https_port = 443
privilege_mode = true
#privilege_token = 12345
max_pool_count = 50
log_file = ./frps.log
log_level = info
log_max_days = 3

frpc：

[common]
server_addr = *.*.*.*
server_port = 7000

[web_https]
type = https
custom_domains = *.*.*

plugin = https2http
plugin_local_addr = *.*.*.*:80

plugin_crt_path = ./abc.pem
plugin_key_path = ./def.key
plugin_host_header_rewrite = *.*.*.*
plugin_header_X-From-Where = frp

请老师们帮忙看看。要穿透的内网机器上的服务也没改==就突然不好使了。
谢谢老师们。
