Website not displaying to certain people

I've created my first website recently and spent the night last night figuring out the backend. I got my domain name through porkbun, set up a droplet through digital ocean and after some tinkering, got everything up and running. I checked it out on my phone, my wife could see it, my mother in law and some friends confirmed it all seemed to be working. Now I contacted the friend I built the site for and let her know it's working, and she can't see it. I sent her the link and clicked it myself to confirm no misspellings, I double checked with other people and they can see it. She's attempted with multiple devices in her household and the only thing she can see is the pork bun "this domain is registered with us but nothing is here yet" page. Her husband also just tried on his cellphone and got a server not found page. I'll attach some photos but I'm completely lost here. www.projectdesignco.ca if anyone else wants to test and let me know or has any inkling what's wrong
