HTTP works, HTTPS doesn't

I’m using Truenas 25.04.1, but this issue has persisted even in previous versions. I’m a bit of a n00b when it comes to this stuff, fair warning. I have a domain run through Cloudflare, and I have cloudflare tunneling set up with my Truenas Server (I really don’t care about the security aspect of it at this moment in time). I also have a couple apps set up (like Plex, Immich, etc.) and I have them also tunneled to my domain. These tunnel domains all work with HTTP, but only the tunnel to my Truenas Dashboard works with HTTPS which is a problem because I can’t access any of these apps with a mobile or tv app via HTTP. I’ve tried getting an SSL set up, but that just isn’t working either. I’m 99% certain the issue is with how my Truenas Server is connected to my network. When I input the hostname and domain, it just comes back as unavailable “this address does not exist.” My network setup is that weird att fiber setup that doesn’t give me much wiggle room, and I’m not able to bypass it.
