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.
I ran this command: $ sudo certbot renew --dry-run
It produced this output:

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.
My web server is (include version): (GNU/Linux 4.4.0-1013-aws x86_64)
The operating system my web server runs on is (include version): Ubuntu 16.04.2 LTS
My hosting provider, if applicable, is: AWS
I can login to a root shell on my machine (yes or no, or I don’t know): No
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No
just create the challenge test file therein:
create the directories along the path (in case they have been removed): mkdir /var/www/html/.well-known/ mkdir /var/www/html/.well-known/acme-challenge/
and then create the test file: echo 'test file' > /var/www/html/.well-known/acme-challenge/test.txt
make sure it is there: ls -l /var/www/html/.well-known/acme-challenge/
then test it from the Internet: http://www.twintec.com/.well-known/acme-challenge/test.txt
Normally you can run individual commands as root by prefixing them with sudo.
In the specific case of the echo ‘test file’ > /var/www/html/.well-known/acme-challenge/test.txt command that @rg305 suggested, prefixing it with sudo won’t work for reasons that I suggest you look into when you have more command line background.
Instead, you can get a root shell with sudo -s and then enter all of the commands into that root shell. Then they will all run as root.
Tried the renew dry run again this morning and it’s producing the following error:

Wow!
Check the log file for more details.
If it lacks good detail, try adding debug: sudo certbot renew --dry-run -debug
and show the /var/log/letsencrypt/letsencrypt.log
