Fake LE Intermediate X1: invalid certificate created by certbot


Hi guys. I’ve created certificates by certbot, but they are not valid for some reason.
Could you please suggest what is wrong here?
I’ve provided all the needed information below. If you need more details, please feel free to ask.

My domain is: stage.timebarter.co

I ran this command:
docker-compose run --rm --entrypoint “certbot certonly --webroot -w /var/www/certbot --staging --email pavlo@timebarter.co -d stage.timebarter.co -d www.stage.timebarter.co --rsa-key-size 4096 --agree-tos --force-renewal” certbot

It produced this output:
ARNING: Dependency conflict: an older version of the ‘docker-py’ package may be polluting the namespace. If you’re experiencing crashes, run the following command to remedy the issue:
pip uninstall docker-py; pip uninstall docker; pip install docker

Hi @pivanchy

you have installed the test certificate from the stage system. This is signed by Fake LE.

So create a certificate from the productive system and use that.


The “–staging” part of this command is what’s causing your cert to come from the test CA. Remove that and you should be good to go.
