My domain is: liedra.net, notjustagame.eu
I ran this command: sudo certbot renew --dry-run (and --force-renew, and many other things which all produced the same result)
It produced this output:

Hi all,
I’ve been struggling with this today with a certificate that expired (I got super busy and didn’t get time to renew it before it expired) - all the previous help has focused on port 80 not being accessible, but I can access port 80 with no problem. I’ve tried all kinds of things - certbot --force-renew, certbot --apache, etc. but I keep getting the same error as above. I’m at my wits’ end! 
It was a long time ago that I set this up so I can’t remember what I did initially to set it up.
Thanks for any help!
