Cert not getting installed on homeassistant running on raspberry pi 3http://bkraspberry.duckdns.org:8123/

I am trying to install security certificates, running home assistant on raspberry pi 3 with python 3.7.3. There is no public IP, using duckDNS. Also created port forward on the router for port 80 and also for port 443. I try to run command as shown below and still get the error. Any pointers will be appreciated, thanks

My domain is: bkraspberry.duckdns.org

I ran this command:./certbot-auto certonly --standalone --preferred-challenges http-01 --email abc@hotmail.com -d bkraspberry.duckdns.org

It produced this output:
Requesting to rerun ./certbot-auto with root privileges…

Certbot has problem setting up the virtual environment.

We were not be able to guess the right solution from your pip

Consult https://certbot.eff.org/docs/install.html#problems-with-python-virtual-environment
for possible solutions.

My web server is (include version):

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

My hosting provider, if applicable, is: duckdns.org

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

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):

Hi @bhavneshk

Please see this other thread: ./letsencrypt-auto failed due to hash problems

There’s a problem with Raspbian/pip and certbot-auto.

Thanks for the prompt response, i followed the step and removed pip.conf file , it helped me to move ahead but resulted in another error as shown below. I have also created port forward on the router for port 80 and also for port 443 (one at a time) but no luck.

If I try to connect to that site over HTTP, it times out. If I try to use HTTPS, I get a “connection refused” error.

It seems like port 80 is blocked by a firewall. (And port 443 is probably unfiltered, but there’s no HTTPS web server set up yet.)

Are you sure you don’t have a firewall blocking it?

Does your ISP block port 80?


over http it was timing out because server was not running, i just bring the server up and it can be reached at http://bkraspberry.duckdns.org:8123/

ISP do block port 80, i just reconfirmed this by checking on my ISP website.

I was under impression that I am trying to get this certificate so i can secure my connection from http to https, are there any pre-steps that i need to take to enable it for https configuration (I have SSH enabled on raspberry pi configuration), please suggest. Thanks!

Unfortunately that means you won’t be able to use the HTTP-01 challenge to prove you own the domain in question. You’ll have to look at using DNS-01 or TLS-ALPN-01.

Presently Certbot doesn’t have support for TLS-ALPN-01 so to use that challenge type you would have to switch to a different ACME client.

I believe DuckDNS allows setting TXT records but I’m not sure if there is an easy plugin to use with Certbot or another ACME client.
