Problem getting Lets Encrypt certificates to be created

[keda82]

Selfsigned certificates works but not "public" Lets encrypt certificates. My guess is that my DNS/Domainprovider(Loopia) requires authentication via API to allow for generation of certificates. Is it possible to add this to the config somewhere? Or can I do it manually?

• My domainname resolves to the correct external IP
• Running this on a Virtualbox image with bridged network
• Port 80,443 and 8080 is opened in FW and forwarded to bridged network adress (virtual box)
• When I ran selfsigned certificates I was able to get resolve the matrix.domain.name and element.domain.name

Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 8080. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.

I have noticed that my host OS(ubuntu) is on 192.x.x.x and I have port forwarded 80 and 443 to the host adress. Could the issue be that 192.x.x.x:80 is not forwarded to 172.x.x.x(docker container)?
