No one can access my website unless they are in incognito mode

So im making a website and i bought a domain from dynadot but no one can access it, im using passport and passport-discord maybe thats the cause? im not really sure but im using repl.it for hosting, without linking the domain it works 100% fine but when i link it it just fails, ireally have no idea what causes this problem, i cleared my cookies n everything but the same results happen, even on my other devices or other browsers
