Custom Domain Mapping getting failed
With error:
Saving debug log to /home/frappe/.certbot/logs/letsencrypt.log
Requesting a certificate for demo.tetsd--emo.com
Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:
Domain: demo.tetsd--emo.com
Type: connection
Detail: 1.1.561.1.1: Fetching http://ssl.tescloud.cloud/.well-known/acme-challenge/ygHT3SlQ0S7mctw1Xpspn-KFselgupPn6j2EDdDqEOU: Redirect loop detected
Hint: The Certificate Authority failed to download the temporary challenge files created by Certbot. Ensure that the listed domains serve their content from the provided --webroot-path/-w and that files created there can be downloaded from the internet.
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /home/frappe/.certbot/logs/letsencrypt.log or re-run Certbot with -v for more details.
@corentin can you please look on this?
Hey 
-
Check that the DNS records point to your Frappe Press central instance.
-
Add the following Nginx configuration (e.g. /etc/nginx/conf.d/ssl.conf).
# ACME Challenge for all TLS certificates
server {
listen 80;
listen [::]:80;
server_name ssl.example.cloud;
location ^~ /.well-known/acme-challenge/ {
default_type "text/plain";
root /home/myuser/.webroot;
}
location = /.well-known/acme-challenge/ {
return 404;
}
location ^~ / {
root /home/myuser/.webroot;
}
}
-
Reload the Nginx configuration (service nginx reload).
-
Go to the TLS Certificate for the custom domain that fails.
-
Click Obtain Certificate.
-
Wait a little bit.
-
On failure, look at the error log for a TLS Certificate Exception, and look at the connection Detail Type: connection\n Detail: IP ADDRESS and check that the IP is that of the Frappe Press instance. If not, maybe the DNS records are not yet propagated.
