Not Getting "SmartThings Hub Communication Established" 
Hi,  This morning, all the device in my homebridges did not work.  So I restarted homebridge and it's not working.  I removed all the devices to reduce it down to one device, but it still is not working.  I'm using a raspberry pi 3 and my smartthings hub is in the same network using IPv4 addresses
i also did the npm update homebridge-smartthings -g  && npm update homebridge -g

Is there any helpful hints I can do to troubleshoot more? 

I went into smartthing web api site to look at Live Logging, and I'm seeing it attempt to connect to port 8000:
dddddddd-dddd-425e-8770-a2ea4a75e5f9  2:22:10 PM: debug Trying 192.168.1.111:8000
dddddddd-dddd-425e-8770-a2ea4a75e5f9  2:22:10 PM: debug Command Request


Here's  what happens when i started homebridge on my raspberry pi



pi@raspberrypi:~/.homebridge $ homebridge -D
