I’m using “Network Lobby” asset for unity and trying to make webGL build with using WebSockets. When I create a game or get a list of servers I get the following error:
XMLHttpRequest cannot load https://mm.unet.unity3d.com/json/reply/ListMatchRequest. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘my_domain_name’ is therefore not allowed access.
Is it a problem on the server or on the client? And how can I solve it?
