I have spent a lot of time with attempts to build unity3d project for browser(web player / web gl).
Web player crashes with "content was stopped because a fatal content error has been detected". http://185.46.9.211/web_player/web_player.html
Web GL not working with strange js exceptions. http://185.46.9.211/web_gl/index.html
Unity 5.3.1. Unet or PUN(latest from asset store) for networking. Windows 7 x64.
Windows build(exe) works fine in multiplayer mode.
Could you please explain the reason of problem in webgl or web player? Could you recommend some working tutorial?
Problem was solved. Bug was in unity 5.3.1. Version 5.3.2 works fine
