AcmeClient: validation for certificate failed

[beckzg]

I have a fresh new install version 23.1.2 and I'm trying to implement acme client with HTTP challenge type.

AcmeClient: validation for certificate failed: <my domain fqdn>
2023-03-08T09:47:38   opnsense   AcmeClient: domain validation failed (http01)
2023-03-08T09:47:27   opnsense   AcmeClient: using challenge type: HTTP
2023-03-08T09:47:27   opnsense   AcmeClient: account is registered: ******@gmail.com
2023-03-08T09:47:27   opnsense   AcmeClient: using CA: letsencrypt
2023-03-08T09:47:27   opnsense   AcmeClient: issue certificate: <my domain fqdn>

Any idea what should be the problem? I checked everything, the light httpd is running, the firewall is open for port 80 and 443, the opensense web ui port changed from 80/443 to 8443.

Bump, I have the same issue but using DNS01 as the validation.

I was able to go back into each certificate and click on renew/issue to fix the issue.
