Online multiplayer issue with aarch64 flatpak

I am unable to make an online game for others to join when they are not on my local network, however directly inputting the IP when on the same network works perfectly. The created game shows up on ms.srb2.org, but under Ping it has an error that says "unable to connect" when the mouse is hovered over it. I am using the Flatpak package on Manjaro using a Raspberry Pi 4. I do not know if this issue is present on x86_64 computers as at present I have none available to test it on.
