Hi. Brand new to DO. I just installed NextCloud in my first droplet using a self signed SSL cert on the server IP address. All works as expected. :)
Now, I have added a sub domain on my (external to DO) web hosting company (VentraIP) and set the A record there to point to the DO IP address. It works fine, resolving to the DO Nextcloud server instance as above.
So… now I want to use Lets-Encrypt to make it secure. When I follow the instructions to setup the SSL
sudo nextcloud.enable-https lets-encrypt
I get the error:
Domain: cloud.mydomain.com.au Type: unauthorized Detail: During secondary validation: Invalid response from http://cloud.mydomain.com.au/.well-known/acme-challenge/8jH3_HtiUcMwEn1yJ9nQQ21TON6tApEBmw-44h3unas
(where cloud.mydomain.com.au == my real subdomain name)
The subdomain is listed in the Trusted Domains.
The firewall port is openned.
What have I missed, do you think? Thanks, Murray

Hi there,
Right after the Invalid response from line, do you get any other output? Usually, right after that line, there should be a more detailed message with the exact response and reason why Let’s Encrypt is failing to validate the domain name.
In most cases, it is due to the A record of the domain not matching the server IP address.
