Need assistance

It's been about 15 years since I really messed with anything. I developed a port of the custom root and recovery for the Motorola Defy way back when dinosaurs were roaming. And I haven't done much since then, so I forget a lot. I have an HP Elitedesk 805 G6. I installed Debian 12.6 Bookworm, and then YunoHost. I have it set to be accessible via my domain I pay for already. I opened the ports it said to open when I ran my diag from my YunoHost admin dashboard. But I can't access my apps from another machine. I can access my dashboard from another machine, and run diag and it shows my ports are open, so I'm not sure what the problem is. I just get the standard website not found. I'm following the domain it shows in my YunoHost dashboard under that app I'm trying to access.
