HD300 and HD200 Cannot Connect

[OldPCGUY]

Free Case Of Beer to anyone who can help me solve this problem.

My HD300 and HD200 Both stopped connecting to my Sage Server at the same time two weeks ago.

Both have the same symptom. I stop the auto connect on either HD box and see if I can link to my Server's C drive. This is no problem for either HD200 or HD300. But both identify my Sage Server by Name and then I try to connect.
Both boxes say they are connecting and then the screen goes blank and Sage never comes up.

Power Cycle HD200 & HD300, Power Cycle Server PC power Cycle Netgear box. Still 100% Fail to Connect.

Verify Network Connection is good. Fire Tablet connects, Samsung Smart TV connects, Android Phone connects. And both HD200 and HD300 have valid IPs and can see the server.

There is no signature of the failure that I can see on the Sage Server to tell me if there is a problem. So I tried the following.

1. Save current Sage Directory on another Hard Drive.
2. Complete Removal of Sage Software from Server
3. Install Latest Version of Sage 9
After this was done I got the HD300 to connect a couple of times. But then
4. Updated HD300 Firmware
Now back to 100% no connection on HD300
5. So I cleared the Sage install again but still no connection

Next Steps
1. Provide Direct Ethernet Cable Connection to Router and then
2. Direct cable connect from HD300 to PC

Does anyone have any ideas on to root cause this problem?
Is there any way for me to see what the HD300 signature is when it fails to connect. Is it stuck in an infinite loop? Did it forget to turn on the HDMI output? Is there a failed to connect message on HD300?
Can I hook up a laptop to the HD300 and get more information from it while it is trying to connect?
