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: www.modularservices.com
I ran this command: N/A
It produced this output: N/A
My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is: pantheon.io
I can login to a root shell on my machine (yes or no, or I don't know): No
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): Pantheon control panel
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you're using Certbot): Unknown.
Pantheon hosts our www.modularservices.com and subdomains, secured by Let's Encrypt. All working here. Problem is, we need a PFX file for a subdomain that won't be hosted on the Pantheon servers. Pantheon is unable to provide a PFX file. How can I create a PFX file without access to the private key?
Pantheon will allow me to purchase a Gold Support plan to allow a installation of a custom wildcard SSL. I can generate the PFX if I supply the wildcard SSL, but it comes at a hefty annual price for their Gold level support which we don't need. It also isn't a "Custom SSL." It is securing the same domain and subdomains currently protected by Let's Encrypt. I just need a PFX file for the other host.
Is it possible to generate a PFX key with Pantheon being the host of our domain?
Any help is greatly appreciated!
