Trying to connect to a server using StartClient() crashes a WebGL build with error messages that mention pthreads. Something I would not expect Unity to be dealing with in a web build. Has anyone had any success with Unet and WebGL, is this an issue with the LLAPI or can it be avoided by using the LLAPI?
StartClient() is a HLAPI function. It is known issue and webgl ream is working right now for fix. Hence, LLAPI works, you can check it wit demo project see LLAPI.zip in UNet Sample Projects - Unity Engine - Unity Discussions
