I've been trying and failing to set up SSL using Let's Encrypt on a Mac.
I was trying to follow this recipe.
My Subsonic Server is still running High Sierra (10.13.6)
I was able to install Certbot using Homebrew.
I generated certs using: sudo certbot certonly --standalone
I gave my dyndns.org domain name.
After that, I was able to follow the previously mentioned recipe (I had to install a JDK first).
When I enable https in the /Applications/Subsonic.app/Contents/Info.plist file, all I get when I go to my server is a 404 error.
If I revert back to Subsonic's self signed cert, https works but, of course with the self signed cert warning.
I'd really love to be able to figure out how to use a Let's Encrypt cert with Subsonic on High Sierra. If anyone out there knows how to do this, please help. Thanks.
