Hi!

Are you using the wildcard cert method or the standard install with http verification?

No just the standard install with HTTP-01

Hi, sorry for the delayed response.

My guess is that your Traefik instance isn't fully accessible over HTTP/HTTPS likely due to not having the ports open and/or having the DNS records set up. As a first troubleshooting step, can you confirm that you have ports 80 and 443 open on your VPS and your VPS also has a public IP? Also, please check that you have an A record with your DNS provider pointing all subdomains to your VPS public IP. Here is a screenshot of how I did this in Cloudflare.

If you have this set up and still have the issue, let me know and I can help you troubleshoot further.
