Server Terrain/world not loading,  blank inventory and then force disconnected from realm.

What I expected to happen was...:
Loading into the server I have played on

What actually happened was...:
The terrain will not load, I only see the sun and sky.  Inventory is all gone, including armor, and then after 30 seconds or so I am disconnected.  Sometimes it says "Connection Lost - Disconnected" other times it says "java io.ioexception forcibly closed by remote host"

Steps to Reproduce:
1. Log into my friends Server Realm - Blank World and Inventory, then disconnected

My Attempts to Fix:

I have tried restarting the game, my computer, the router.  Turning on and off the Firewall, enabling the native sandbox in java, all to no avail in fixing the issue
