I just straight up gave up trying to automate renewing my wildcard certificate from Letsencrypt after who knows how many weekends. Typing a single command won't kill me lol
That's the easy part, the hard part was getting the acme-dns authentication to work since you can't use the regular automated update with a wildcard certificate.
What exactly are you having trouble with? I've automated all of our LetsEncrypt renewal stuff at work, including certs for wildcard domains, and it's using the DNS plugin.
Honestly I've sunk so much time into this that I never want to think about it again if I can just run a shell script once every 3 months haha. I never understood the process too well.
