SSL Cert?

[amzrigh]

Hey, I'm a bit of a noob. I suspect my problem might be related to that previous issue, but I can't swear to it, so I'm posting separately. I'm attempting to install and run this on a Raspberry Pi 4 running the latest version of RPi OS.

When I follow the installation procedures and attempt to navigate to the device in my browser, I get a ERR_SSL_PROTOCOL_ERROR, site can't provide a secure connection. I don't have any other web services that didn't just work straight out of the box, so between that and googling the error, it sounds like I don't have an SSL cert, and I need one. Is that right?

And if that is right -- every guide I can find says to put the cert files in a different location, and I can't verify which would be the right place for it to work here. I've tried mapping the files to the caddy container, since that's the one using port 443, and I've tried looking around in there for any config where it might tell me where it's looking for a cert.

I don't even know if I'm going about this the right way, but I'm trying, dangit, lol. Please help.
