Login page not loading

Nextcloud version 21?
mariadb 10.5
debian 11

The issue you are facing:
All of sudden the nextcloud login page won’t load in any browser. I also can’t access via the phone app. a week or so ago I uploaded to the latest version via the settings panel.

It seems there is some problem with the ssl certificate. I use let’s encrypt. The output of tail /var/log/apache2/error.log, listed below, lists two unmatching ip addresses which I blocked out but they are different.
Nextcloud is installed on a subdomain on my vps. The main domain is just some simple html and works fine. The other sub-domain has wordpress installed and has the same issue.

Does anyone know how I might troubleshoot this?

Thanks in advance

Is this the first time you’ve seen this error? (Y/N):
Steps to replicate it:

1.When I go to the login page it never loads
