Error during WebSocket handshake

[artknight]

@isapir reading the thread (#12) I am a bit confused on the whole installation process. Please correct me if I am wrong

Step 1: Go to the Lucee Admin and install the Websockets Application 2.0.3. That should be it?

• Do I still need to copy/paste the servlet-filter-utils-1.1.1.jar into the tomcat/lib directory?
• Do you I need to add the code below to web.xml?

<!-- Required for the Lucee WebSocket Extension !-->    
    <filter>
      <filter-name>HttpSessionInitializerFilter</filter-name>
      <filter-class>net.twentyonesolutions.servlet.filter.HttpSessionInitializerFilter</filter-class>
    </filter>

    <filter-mapping>
      <filter-name>HttpSessionInitializerFilter</filter-name>
      <!-- modify url-pattern to match your websocket endpoints !-->
      <url-pattern>/ws/*</url-pattern>
    </filter-mapping>

I am getting a 200 handshake error that I can't seem to resolve.

VM723:1 WebSocket connection to 'wss://mysite.com/ws/meetings' failed: Error during WebSocket handshake: Unexpected response code: 200

Thanks!

@isapir So as a follow up, I was able to get it working successfully by adding a location to the nginx config

location /ws {
  proxy_pass http://127.0.0.1:8888;
  proxy_http_version 1.1;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
  proxy_set_header Host $host;
  proxy_set_header X-Forwarded-Proto $scheme;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

However, now after reloading the application scope onApplicationStart() I get a 404 error

WebSocket connection to 'wss://(...)/channel' failed: Error during WebSocket handshake: Unexpected response code: 404

The only thing that fixes it is to restart my tomcat. Very strange!!!

It almost feels like running this code the second time does not allow for the websockets to be registered
websocketServer("/ws/chat/{channel}", new ChatListener());
