hr-stream | time heart rate visualizer to XSplit/OBS/Etc streams | Stream Processing library

I will first start with what I am aware of, as it may be useful for the rest.

It is clear that you can instantiate SockJS with a subset of protocols:

I need to send the token when the handshake happens with SockJS. I've tried many suggested implementations but the same exception is called

I have a spring websocket chat application . in some client i get this exception and dont know why websocket dose not connect and sockjs change to xhr-stream and again dose not work ,all client have antivirus but some of them have this problem this is my stack trace and exception.when i uncheck web control in antivirus (kasper or mcafee) application work correct

I'm trying to get webpacker working with docker, puma 3.10.0, rails 5.1.4, and webpacker 3.0.1.

I have the following config set up for docker:

Dockerfile

Background: using Vertx 3.3.3 Core and Web on Java side as a server, using vertx-web-3.3.3-client.js as the client with sockjsclient1.1.2.js

Issue: I am successfully making a connection to the eventbus from the client when on my local machine or LAN. When I go through a proxy, the wss eventbus connection is being blocked (in Firefox I see "Firefox can't establish a connection to "wss://..."; in Chromium I see "WebSocket connection to wss://... failed: Error during WebSocket handshake: Unexpected response code: 400", then I see "https ://.../eventbus/.../xhr_send?t=... Failed to load resource: the server responded with a status code of 500"). However, the onopen fires and I receive some data (connection downgraded to an accepted protocol?). Immediately after this, onclose fires and I have lost connection. I know that I am successfully reaching the Java vertx server because my static web and API calls are working.

Questions: I have looked through the Vertx and SockJS documentation extensively. Is there:

1. Documentation on how vertx tries different transport protocols in the JS Eventbus connection?
2. An example of JS Vertx Eventbus working through a business proxy?
3. Another way to implement the Eventbus connection, perhaps specifying the SockJS protocol(s) to try/use? (I am trying the simplest way to create an eventbus connection, as shown in many places in documentation)
4. Something I need to do on the Java side of the SockJS/Eventbus setup?

Thanks in advance for any advice/help!

EDIT 1: Adding the following code for both Java server and JavaScript web client sides. The web side is very basic (and what is failing). The Java side is using Spring for dependency injection and application config, has an Eventbus connection, one API call, and serves static web content.

The API call from client to server works, and the server sources the web contents correctly, so accessing the tool is working. However, the proxy is causing wss to fail (as expected) but the downgrade to xhr-streaming is failing (I think)
