当我使用acme(version v3.0.6)命令颁发证书时:
export Namesilo_Key=812bb423232b951sdfwg3423
acme.sh --issue -d reddwarf.life -d www.reddwarf.life --nginx --debug --dns dns_namesilo -k ec-256
acme进入无限循环，这是日志输出:

它显示Not valid yet, let's wait 10 seconds and check next one.和检查永远，哪里出错了?我应该怎么做来解决这个问题?最后我发现，也许dns需要一些时间才能生效。但是最后用下一步来解决这个错误:

此消息来致命故障reddwarf.life:Verify error:"error":{.
最后我发现nginx服务器将端口80重定向到443，这是遗留配置:
server {
listen 80;
server_name reddwarf.life;
rewrite ^(.*)$ https://${server_name}$1 permanent;
location / {
try_files $uri $uri/ /index.html;
}
}
我删除了重写配置，问题解决了。
