Beta4.3.79 Error: Failed to receive data

There was an error checking for updates to the A* Pathfinding Project
The error might disappear if you switch build target from Webplayer to Standalone because of the webplayer security emulation

what’s the Webplayer? I’m running my game on unity play mode.

This might be a Unity bug, or it could be some security emulation for the webplayer platform. I have never seen it before.
In any case, this is only for the A* Pathfinding Project’s update check, so ignoring it is completely safe.
