Help with running private server client via web

SO let me explain the image basically first browser is running locally and it connect and lets you pick a char/account but it hangs at the screen you see.
Second browser is accessing my website from the web and the client loads (gets sound) but has an overlay that stops it from working

Third is the client im pushing to my webpage in a projector (works fine)

Fourth client is ran in a VM with google chrome and connects fine aswell.

All clients are the same file all with my external ip

Server DNS is also my external ip
