Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: rentals.blizzardinternet.com
I ran this command: certbot certonly --manual --preferred-challenges=dns -d rentals.blizzardinternet.com
It produced this output: Provided a cert/key/bundle after passing the ACME DNS challenge.
My web server is (include version): Server version: Apache/2.4.18 (Ubuntu) | Server built: 2019-09-16T13:13:53
The operating system my web server runs on is (include version): Ubuntu 16.04.5 LTS (Xenial Xerus)
My hosting provider, if applicable, is: We have a dedicated hosting environment at Rackspace
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): certbot 0.31.0
Using certbot, I generated a certificate which is now erroring due to the expiration of the Let's Encrypt R3 cert. I was hoping this could be resolved using certbot but it doesn't appear it can. Our Ubuntu version is old but I believe it will still do the job for this issue. We are phasing out this entire infrastructure at Rackspace and will not be able to upgrade the OS. Is this a simple matter of my downloading the intermediate certificate and using it in place of the one certbot generated earlier? Our certs are managed on a brocade at Rackspace and we don't have access to the configuration. Thanks for any insight to my newbie questions.
