Custom domain not working

So I've been trying to get this custom domain to work for what's probably been 2 months now. I've removed it, added it, let it sit for a day, removed dns records, add dns records. Nothing seems to work, now I'm stuck on a Certificate generation started screen.

This is quite frankly pissing me off because I've been trying for so long to get this to work.

For those with access the domain I'm trying to use is portfolio.flamality.com.

Thanks for any help 🙏
