Renew Expired Cert - The client lacks sufficient authorization

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. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: birdiedex.com

I ran this command:

certbot renew --dry-run

It produced this output:

IMPORTANT NOTES:

My web server is (include version): nginx/1.10.3 (Ubuntu)

The operating system my web server runs on is (include version): Ubunto 16.04

My hosting provider, if applicable, is:

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): certbot 0.31.0

There is a LightSpeed server answering on IPv6 (which is prefered by Let's Encrypt), while at your IPv4 address a nginx server answers.

Looking at the fact you're using the nginx authenticator and installer plugins, your IPv6 address with the LightSpeed server is incorrect.

Thanks for the quick reply. How can I update the IPv6 address?

I don't know how you usually edit your DNS zone, but that should be done in DNS at the DNS zone editor of your DNS provider.
