Incomplete authorizations

Hi all, having a bit of an issue here!

My domain is:

I ran this command:

sudo certbot certonly --standalone --preferred-challenges http --http-01-port 80 -d -d --debug

It produced this output:

Starting new HTTPS connection (1):

My web server is (include version):

HA-Proxy version 1.6.3

The operating system my web server runs on is (include version):

Ubuntu 16.04.4 LTS

I can login to a root shell on my machine (yes or no, or I don’t know): yes.

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

Note that I was able to solve the issue by following this guide:

Interesting solution.

But: Normally, you don't need different setups first-certificate versus renew certificate.

So you can always use the http-solution.
