Issue The website not appearing on mobile.

[hakanmessi]

I purchased a domain from GoDaddy and am using Plesk for hosting. I've developed my site using the MVC method with ASP.net. After setting up the site and DNS binding through Plesk, the site works fine on browsers opened on a computer, but it doesn't work on mobile browsers. Despite trying various options, I couldn't identify the reason. If there are people experienced in this matter here, I really need your help.

On mobile, the GoDaddy default page appears, but on a PC, I can see my site normally. I truly need your assistance.
