Need help fixing a websocket communication error between laravel copy trading app on Linux VPS and NJ4X program (Java/C#) on remote Windows Server

MQL4 Other C# Java PHP

Specification

I have a Windows copy trading app (in PHP and Laravel) residing on a Linux VPS trying to communicate to a NJ4X program coded in Java/C# that resides on my two Windows 2008 remote servers. The communication has been fine for 2 years till 4 days ago.  

Recently, the Java/C# program residing on the Windows 2008 Servers have been giving me the following errors:

On the one Windows Server: 
WebSocketServer: handleConnection<> HTTP status: 400 error: Error Reading HTTP request
WebSocketServer: handleConnection <> HTTP status: 400 error: Missing Sec-WebSocket 

On the other Windows Server: 
WebSocketServer: handleConnection<> HTTP status: 400 error: Error Reading HTTP request
 WebSocketServer: handleConnection <> HTTP status: 400 error: Missing Sec-WebSocket key value
WebSocketServer: handleConnection <> HTTP status: 400 error: Invalid HTTP method, need HTTP/1.1, got: HTTP/1.0


I believe the problem is with something misaligned on the Windows Servers, but I'm not sure. I would like an experienced developer with PHP and Java / C# experience to see if he can trouble shoot through this issue. Ideally, he can fix the web socket issue so that the Laravel app can effectively communicate again with the desktop programs on my Windows servers.
