I have a minipc with proxmox on it. I have tried caddy in a lxc to set up DNS challenges to my owned domain and I set the url in my router to point to the IP (for example, proxmox.DOMAIN.com could be 192.168.10.22). The hope was to have everything local within my house and nothing needs the internet to be accessed. Some services I can host in proxmox NEED https to use, which I could not get working with my own certs or ones proxmox could make, thus Caddy. However, I get proxmox with a proper cert, but i cannot get any of the other services from proxmox working. If I were doing it all manually, I would expect DNS issues with the domain, but from what I understand, Caddy by default does wildcard domains which should mean that my services should work. but they do not. Networking is new to me so perhaps I am missing something obvious. Any guidance would be appreciated.
EDIT: You guys helped me find my issue! Turns out that I did everything right except for 1 simple step. Once I have everything set up, I have my router point the urls to the CADDY address, not the services address. For example, I had bookmarks.DOMAIN.com set in my router to point at the readeck lxc ip and it didn't work. Changing that to the Caddy ip fixed it. So all my services would point to the same ip (caddy). I do not know how I never saw this in any of the tutorials/videos/guides I checked, but THANK YOU for pointing it out to me.
Now the only odd thing is why does the proxmox ip work fine without pointing to caddy? I will leave it as is, but its the odd one out :/
Yes, I probably did. I am familiar with computers, but know next to nothing about networking. So I was trying a bunch of various things I could find to try to get it to work. the proxmox ACME did not get me certs for my server or for a vm of proxmox so I abandoned that method and tried caddy and GoDoxy but never got them to get certs for services after various attempts. So I reached out here since there are many more people smarter than me here.
