My domain is: z0m.bi
My web server is (include version): nginx/1.18.0 (Ubuntu)
The operating system my web server runs on is (include version): Ubuntu 22.04.3 LTS
My hosting provider, if applicable, is: Digital Ocean
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 1.21.0
Issue started when I moved my site to a fresh VM. I wanted to swap over to the wildcard DNS domain authentication method which I've used successfully for other sites. I don't remember all of the things that I've done at this point, but what seems to be occurring is even tho my certificate is renewing correctly (visiting crt.sh shows that it shouldn't expire until June) the site itself has a certificate that shows it expired a week ago. I believe what's happening is the old method of the certificate is linked to the site, because it never asked me to set up TXT records to authenticate the certificate like it has for every other site I've used the wildcard DNS setup on. idk how to fix this conflict, can I remove the certificate and start fresh somehow?

Please provide the actual commands used to get the certificate. For some reason you seem to find it necessary to remove those questions from the questionnaire.
Note that if you try to renew with the --dry-run option, you can check if the authorization step is actually working. This is because valid authorizations are cached for 30 days, but the --dry-run option actively deactivates currently cached authorizations on the staging environment. (This won't work for production, but testing on staging should suffice.)

What's the contents of /etc/letsencrypt/renewal/z0m.bi.conf and did you reload nginx after renewing? (Although the latter shouldn't be necessary as the nginx configuration suggests the usage of the nginx installer, but good to check anyway.)
Also, is the IP address of your new VM 164.92.90.64? Or could that perhaps be the old VM?

certbot 1.21.0
It would be necessary to have something reload nginx as it wasn't until v1.27.0 that --installer nginx would cause a reload by Certbot.
We know they aren't using --nginx as an authenticator as their certs are wildcards.
1.27.0 - 2022-05-03
@z0mbi It will be very helpful to see the renewal config file @Osiris asked for. And also to verify the DNS IP.

That's only when certonly is used, but the nginx configuration mentions "# managed by Certbot", so the nginx installer is actually used without certonly, at least, somewhere in Certbots usage. It's currently unknown if that's actually the case for this certificate (the comment in the configuration might just be an artifact from the previous setup), so we'd need to see the renewal configuration file to know it instead of guessing
Also, it doesn't really matter for renewals, as a renewal is a different subcommand than certonly, so if the installer is actually configured as such, it should reload nginx.

The contents of /etc/letsencrypt/renewal/z0m.bi.conf is:
# renew_before_expiry = 30 days
version = 2.9.0
archive_dir = /etc/letsencrypt/archive/z0m.bi
cert = /etc/letsencrypt/live/z0m.bi/cert.pem
privkey = /etc/letsencrypt/live/z0m.bi/privkey.pem
chain = /etc/letsencrypt/live/z0m.bi/chain.pem
fullchain = /etc/letsencrypt/live/z0m.bi/fullchain.pem
# Options used in the renewal process
[renewalparams]
account = [accountnumber]
authenticator = dns-digitalocean
server = https://acme-v02.api.letsencrypt.org/directory
key_type = ecdsa
dns_digitalocean_credentials = /home/user/certbot-creds.ini
No, that's the correct IP address.
Yes several times. unfortunately. It is possible that the nginx config certbot bit could be left over from the previous set up, I don't remember at this point tbh.

There's no installer configured nor is there a deploy hook, so manually reloading/restarting nginx would be required. But you did that you said.
Please show the output of sudo nginx -T.

I've managed to get it working after couple more restarts of the server, idk if something is cached somewhere or what. The same thing happened to me last time the certificate expired as well a few months back. I don't know what else to look at, I do have this file /etc/letsencrypt/renewal-hooks/post/reload-nginx.sh which is just:
#!/bin/bash
service nginx reload
as far as nginx reloads go. I guess I'll wait to see if it happens again in June.
version = 2.9.0
Isn't this mean there are two certbots on that server? 2.9 and 1.21?
