Hello everyone! I have a problem with a simple game. It is my first multiplayer project and also one of the first Unity projects in general. For the multiplayer I am using Photon PUN2. In my project I have a host build, where the host can create a room. This one has a usual Windows build. Additionally there is a client build, from which the room(s) can be entered and which should be build in WebGL and later be placed on a website, so that the client users can reach and use it from this website. Now I made a first test and have a problem with the WebGL client build. On my computer, it works totally fine. It works in unity, it works when I open the index.html file in my browser and it works when I put it onto my home server. When I put it onto my home server, I can also run it from other computers in the Network without any problems. But if I take the folder of the WebGL build and try to start the game via the index.html on another machine I get the following error and I do not unterstand why: abort("both async and sync fetching of the wasm failed") at jsStackTrace@file:///C:/Users/[...]/Build/webglbuild_client.framework.js:738:12 stackTrace@file:///C:/Users/[...]/Build/webglbuild_client.framework.js:752:11 abort@file:///C:/Users/[...]/Build/webglbuild_client.framework.js:18:44 getBinary@file:///C:/Users/[...]/Build/webglbuild_client.framework.js:1124:9 getBinaryPromise/<@file:///C:/Users/[...]/Build/webglbuild_client.framework.js:1137:12 I found similar forum threads etc. with similar errors and tested several build settings, but nothing worked. I do not understand, why everything is fine on the machine, where I created the project, but not on any other machine. Let my know if you have an idea, what the problem could be or if you need aditional information.
