If you have redirect port 80 to 443 at nginx.conf ,the renew will failed as
it gave error:
Cannot find config file for domain cloudzhong.top

Though it is already solved by another post
But the solution have issues, that I can only change the config to a renew config then renew certification and then rolled back the config file . to let the config file do not need to be rolled back , I write this post.
For nginx 80 port , add
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name cloudzhong.top;
root /usr/share/nginx/html;
location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}
location ^~ /wordpress/ {
return 403;
}
}
server_name need change to domainname, and root directive maybe is also needed.
and forbidden wordpress folder by return 403
and the below redirect code.
return 301 https://$host$request_uri;
in the server 80 block is not allowed, this is the reason that acme.sh failed. So I delete it here.
add index.html under root folder.
here is the content:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="refresh" content="0;url=https://cloudzhong.top">
<title>it is redirectling...</title>
</head>
<body>
<p>if this page did not redirect , please click <a href="https://cloudzhong.top">Here</a></p>
</body>
</html>
This is the automatically redirect html ,which will works same as return 301 when access domain name by http.
Then you can successfully renew the certification.
