I’m trying to set up a web server on my Raspberry pi at home. I’ve used duckdns for dynamic domain name service.
I know that I’ve got my router’s port forwarding set up correctly because my website works on both port 80 and port 443 at the domain name I’ve set up. I currently have a self-signed certificate instead of a signed letsencrypt one. Certbot claims that I keep failing challenges, what am I doing wrong?
My domain is: volumeup.duckdns.org
I ran this command:
It produced this output:
The standalone specific supported challenges flag is deprecated. Please use the --preferred-challenges flag instead.

The following errors were reported by the server:
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
