Thanks for the reply. Looks PeerJS end as desktop connections also stopped working.
When I first built it, you could cross platofrm online :)
Cordova is just used for building to android / ios
No problem - I'll just have to learn the C2 multiplayer for anything further to bring it back.
Shame, as it felt pretty novel using your PeerJS plugin all those years ago to have cross platform multplayer before it was officially posible
