Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
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.

I forwarded port 80 to my raspberry pi and allow it on firewall using sudo ufw allow 80 but have this error:

To fix these errors, please make sure that your domain name was

contain(s) the right IP address.
When I use —nginx instead of -a manual, it shows:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Could not choose appropriate plugin: The requested nginx plugin does not appear to be installed.
