Gitlab site says to configure Gitlab-CE installation, what can I do get back into my site?

Hello,

I have a droplet set up for a while with Gitlab-CE from a one-click install. I believe Gitlab was at 9.2.5 when I created the droplet.

I have tried to keep the droplet up to date, but today I noticed that the site was not working. There was an error about unsecure connection. I have had this issue before, and it was easily fixed by updating my droplet. I went and did that but still could not get into my site.

I checked the Let’s Encrypt certificate to see if it needed to be renewed with sudo certbot renew --dry-run but that showed these errors:

Attempting to renew cert (gitlab.devplateau.com) from /etc/letsencrypt/renewal/gitlab.devplateau.com.conf produced an unexpected error: Failed authorization procedure. gitlab.devplateau.com (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://gitlab.devplateau.com/.well-known/acme-challenge/HSNFfdwytBVlEdmalsrX1gGxfVn3WtNI0YK8Pm6JtPo: "<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: gitlab.devplateau.com

   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.

I have made sure that the A record for gitlab.devplateau.com did not get removed somehow and it is still there. I even removed it and created it again just to be safe.

Can someone please help me get back into my Gitlab site? I have important code saved and would prefer not to have to start the server over.
