Additional details; thought it was maybe the firewall (based on other posts here in the forum). Added 443 to firewall via plesk, and also did the same via ssh (ufw allow https) – both with no problems. Then tried again with Let’s Encrypt. No luck.
I created a new subdomain, then had Let’s Encrypt secure it to see if the result of securing for the first time would be different from renewing; it was. LE had no problems securing it, no error. So it appears to only affect renewal.
So I’m pretty much at a loss. Any help would be appreciated; thanks in advance for your time.
# ufw allow from any to any port 549 proto tcp

Rule added (v6)
# ufw allow from any to any port 853 proto tcp

# ufw reload
Firewall reloaded
Also added those same ports via Plesk firewall, applied, just in case.
IPv4 and IPv6 for both HTTP and HTTPS are being refused to me now:
curl -Iki4 http://doncullen.net/
curl: (7) Failed to connect to doncullen.net port 80: Connection refused
curl -Iki4 https://doncullen.net/
curl: (7) Failed to connect to doncullen.net port 443: Connection refused
curl -Iki6 http://doncullen.net/
curl: (7) Failed to connect to doncullen.net port 80: Connection refused
curl -Iki6 https://doncullen.net/
curl: (7) Failed to connect to doncullen.net port 443: Connection refused
For now, I need to renew SSL for two domains; I’m running out of time–so I disabled IPv6 in an attempt to get LE to renew via IPv4. It didn’t work. I’d like to get it to renew, then I’ll work with the people at the Plesk forum to solve the IPv6 issue.
Any ideas why it’s not renewing over IPv4?
Edit: Found the problem. It was due to domain registrar still having AAAA record; had to nix that then retry. Worked without issues.
Next step; figuring out why IPv6 is borking. Thanks!
