Main domain not linking?

my main domain isnt working. the replit domain is this. I thought it was a problem with cloudflare but when i linked a new domain (cant link it because new user :/) it worked perfectly fine. Why is this happening?

P.S. by not working i mean this:

I’ve seen this issue before, and I’ve actually had it myself. Try setting your cloudflare SSL setting to “Full (Strict)”.

unfortunately this didnt work
