Our TCP flags have decided that they'd like to change places today; all you need to do is reach the HTTP server!
Roses are red, and SYNs are FINs too.
RST+ACKs are now SYN+ACKs for you.

PSH+ACKs are FIN+SYNs just for the fun.
Hint: If you want to run this challenge from your home or a VM, make sure you are not behind a NAT that could eat your unexpected packets.
