一个非常诡异的反向代理问题

啥配置也不贴，让人干想呢？

server {
listen 80;
server_name a.domain1.com a.domain2.com;
location ^~ / {


proxy_pass http://127.0.0.1/;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Real-Port $remote_port;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header REMOTE-HOST $remote_addr;

proxy_connect_timeout 60s;
proxy_send_timeout 600s;
proxy_read_timeout 600s;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;

}
}
大概这样

看一下 nginx 的日志有没有记录
看一下服务本身是否支持第二个域名访问？

配置第二个域名仅仅是为了演示，a 域名可以，b 域名不可以，单独配 a,c,d 域名都可以，就 b 不行，
