Ok
so first
1. Create An Account on playit.gg
2. Download playitgg agent (playit-x.x.x.exe) The download button is on the header of the website
3. Create A Tunnel Make sure its TCP+UDP or UDP (test it yourself) and the port is 53640 and the local ipv4 address is 127.0.0.1(or the internal ip if you are using 2012M and above clients(the router will give you that address "private ip"))
4. Use the domain name without ip.ply.gg or it wont work for sum reason or its just the delay for me
5. Join with the domain name (example: lake-classics.at.ply.gg)
6. Boom Voila you portforwarded succesfully if you are able to join the server
7. DM Abhidjt#8152(Me Twitter: Abhidjt_tm) or email the support team of playit.gg if you have any issues
Thanks.
