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 Altro C# Java PHP

Specifiche

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.

Should be as it but no alarms, also we need to add a deep search so he can see all the preves candles and a memory function so its not slowing down the indicator. for higher time frames daily 4h 1h around 365 days and for lower time frames we do up to 20k bars but both flexible so i can change it later. the memory is important so the indicator is not always recalculating everything when a new candle shows especially

The EA trades a smart-money-concepts style model (structure breaks, liquidity sweeps, order blocks, fair value gaps, optimal trade entry retracement). Exact parameters and the rest of the underlying logic are proprietary and will only be shared once we're under a working agreement. To check you actually
