Nginx Proxy Manager not able to renew certificate

Configuration
1

Hi,
I know this is asked a lot, but actually I could not find an answer to my specific configuration.
So I’m using the Nginx Proxy Manager addon on my HAOS instance and DuckDNS integration in my FritzBox.
Ports 80 and 443 are forwarded to my HomeAssistant server.
My config for the NGinx Proxy is

# HTTP Config (NGinx Proxy)
http:
  use_x_forwarded_for: true
  trusted_proxies:
    - 172.30.33.0/24
  ip_ban_enabled: true 	       
  login_attempts_threshold: 3

This worked once. Now I’m always getting the error

Command failed: certbot renew --force-renewal --config "/etc/letsencrypt.ini" --cert-name "npm-1" --preferred-challenges "dns,http" --no-random-sleep-on-renew --disable-hook-validation 
Saving debug log to /data/logs/letsencrypt/letsencrypt.log
Failed to renew certificate npm-1 with error: Some challenges have failed.
All renewals failed. The following certificates could not be renewed:

Hi
I think I have a related issue. I don’t use Nginx, however I have Homeassistant running in a Docker set up on rpi4 under Bookworm os accessable through use of duckdns.org I use Lets encrypt for generating new Certificates by running “./dehydrated -c” in terminal every 3 months.
My certificates need renewing today for 1 October 2024.
I tried to do this yesterday and kept getting validation of new certificate failures with code 403. I am running the latest Docker version of release 2024.9.3

Today tried winding back Homeassistant docker image to 2024.6.3 release from June. Again tried to regenerate new certificates and all worked properly!

So I am now investigating why. What has changed and needs fixing before I need to renew again.
Hope this helps in some way.
