Please upgrade to the latest code and try again first. Maybe it's already fixed. acme.sh --upgrade If it's still not working, please provide the log with --debug 2, otherwise, nobody can help you.

浏览器登录下域名，看看什么提示，再查看 /var/log/nginx/error.log 日志，如果是 权限问题的化，修改 vi /etc/nginx/nginx.conf 第一行的 user 参数值 www-data 为你的账户 权限即可
