I’ve read the instructions here https://www.inductiveautomation.com/resources/article/lets-encrypt-guide-for-ignition
I ended up using https://www.win-acme.com/ (I’m on Windows) but I can’t figure out how to create the root CA certificate from what is generated by Let’s Encrypt.
Specifically the part that says:
As of the time of this writing, Let’s Encrypt is using DST Root CA X3 as the root CA cert. Copy its contents to a .pem file in a well-known location on your server and let’s reference it as $ROOT_CA_CERT in this document.
Would anyone be able to give some help on this? Thanks!
