So Im not sure if this is something that can be done.
I have 3 Raspberry PI’s running 3 different servers.
1 Home Automation (home Assistant)
1 Media (torrents, deluge)
1 Personal website. (nginx port 8080)
For the home assistant its xxx.duckdns.org:8123.
For the personal running nginx its xxx.duckdns.org:8080
I use google wifi to fwd the ports. When the Lets encrypt cert expires, I have to run the certbot on each machine. This caused me a few issues and I hit the rate limit a few times.
Is there a way to “share” the certificate across all three machines? Same public IP address
