Bug Description

比如服务器的配置这里SubDomainHost字段子域名是test.frp.com,

然后客户端申请了一个http隧道，子域名是 1.test.frp.com，写在客户端的配置的这里

启动之后，客户端就会收到下面的错误
start error: proxy [8bccb21a898d5958.http] domain conf check error: custom domain [1.test.frp.com] should not belong to subdomain_host [test.frp.com]。

是不是这里的判断有问题，是不是我写错了

你填错位置了。subdomain才是子域名字段，custom_domains 是客户自有域名字段。比如客户可填自己1.aaa.com，才填到custom_domains 。你这种subdomain = 1 就可以了。test.frp.com在服务器填写。subdomain_host = test.frp.com。仔细看frpsfull.ini里面方法挺详尽。

@xingtongsf 好像还是不对，如果客户端subdomain字段只写1，subdomain = frpqwj 这样，提示就是

@superzjg 是的，子域名和服务器上的是一样的，都可以解析到同一个ip

@xingtongsf 我根据我截图的log能看出服务器的这个字段是有设置的，泛域名解析是什么，比如说服务器域名是test.frp.com，那么申请http隧道后会得到一个my.test.frp.com，这个和test.frp.com解析的地址一样的，那么就是设置了*.test.frp.com，泛域名解析。
