Issues with NetPlay: Client cannot connect when going through RetroPie

[Kaydron]

I am having issues with NetPlay.
My friend and I are both using pi4 4gb model. We updated everything at the same time so we should have same core/rom/etc. (holds true because of my later paragraph too).

When going through RetroPie NetPlay setup (which uses the command line arguments to access RetroArch) the host is able to connect and have the port open. On the other hand when the client tries to connect it immediately responds with "Failed to initialize netplay".

I then open the game again but without netplay enabled. Go into the retroarch menu and connect to my friend's pi successfully. There is some wacky things going on with player 1 and 2 controllers swapping when starting a game but i think that is another issue i need to resolve since i believe it happens even outside of netplay.

The odd thing is when i try to do this with my own 2 pis in my local network everything works fine.

I found this post that has very similar symptoms https://github.com/RetroPie/RetroPie-Setup/issues/3161.

I will get another SD card and do a fresh image of RetroPie and have my friend do the same and see if it works with a fresh image.

If you're encountering the same problem as the the one described in the issue, then there's no solutio yet, just the workaround posted in the same issue. The only method that seems to work is to directly connect by specifying the hostname.
