Sudo Certbot renew failed

My domain is: test.buildingmanagementsystems.uk

I ran this command: sudo certbot renew

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): Thingsboard v.3.0.1PE

The operating system my web server runs on is (include version): Ubuntu 18.04.2

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): Yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): 0.27.0

I got an email regarding this certificate as it is now invalid. I thought it would automatically renew. But it obviously has not. When I tried to renew it manually I received the error above.

Hopefully someone will be able to shine some light on this issue as this is the first time I’ve set something like this up.

Thanks,
Gregor

Is port 80 open in all your firewalls?

Hi, I checked my AWS Security group and it only had HTTPS:443 open. I added I’ve HTTP:80 and re-ran the command and it has now successfully renewed the certificate. Will this be why it did not auto renew?

Thanks,
Gregor

Could be. Could also be there wasn’t a cronjob or systemd timer installed. Normally, cron would e-mail you any errors. I have no idea how systemd handles errors.
