What's keeping box-vault-decoder-app.fun from an A

Fix or remove the AAAA record for www.box-vault-decoder-app.fun
Something published an IPv6 address but nothing answers on it, so IPv6 visitors wait for a timeout first. Either make the server listen on IPv6 (and allow ports 443/80 through its firewall), or delete the AAAA record until it does.
