I followed this tutorial on how to install let's encrypt ssl on Google cloud
Everything was working fine before installing but after install the certbot on my WordPress click to deploy site running on Google compute engine,I have only been able to access my website using https://softwarebtc.net , if I use www.softwarebtc.net or softwarebtc.net I receive an error saying server IP not found . I have checked through my cloud DNS to see if it pointing to the right IP, and I see no problem there, I've changed the site setting in WordPress to https://softwarebtc.net it still the same thing.
I'm stuck. Is there a way I can uninstall it.
