Mojave installer

I’m on a Mac 5,1. I’m on high Sierra. I have tried downloading the Mojave installer via apples website on the recommended page under step 4. The App Store never responds. I even tried a clean install of High Sierra and it still doesn’t work. My computer hardware is upgraded and can handle mojave. Why does the link not work? This is very frustrating. Why does apple not just have the downloaders available on the App Store?
