WebSockets | WebSockets Inception | Websocket library

I built a docker container with Django, Uvicorn, Nginx and Redis, and am using django-channels but when I run this it says it cannot connect to the websocket and this is seen in the browser console:

WebSocket connection to 'ws://127.0.0.1:8080/ws/notifications/' failed

It is working fine when I use Django's runserver command for development but when I include Nginx and Uvicorn it breaks.

I know there are a lot of questions and answeres regarding this topic out there, but nothing matched my specific issue.

I am using the following versions

• Angular 10.0.14
  • @aspnet/signalr 1.0.27
• ASP.NET Core 3.1

VERSION UPDATE:

• I just replaced @aspnet/signalr 1.0.27 by @microsoft/signalr 5.0.11 -> same issue.

The SignalR connection works pretty fine until I add an accessTokenFactory in the Angular frontend.

I am running currently a webserver with ASP.NET Core 3.1 and a Blazor project. Recently when upgrading to .NET 6.0 I encountered (even with a blank Blazor project) some problems with a websocket error message in the browser only when deployed on my webserver (see message below).

Locally (on Windows 11 x64, VS 22 Preview 4) there are no error messages...

Webserver: Debian 10 x64, .NET 6.0 SDK installed, running on NGINX with websockets enabled (reverse proxy).

Do I miss out on something or is it a problem with the current state of .NET 6.0 and NGINX? I already tried to access the webpage locally on the debian server and the same error message occurs.

Help would be much appreciated!

Greetings!

I am implementing a simple chatbot using keras and WebSockets. I now have a model that can make a prediction about the user input and send the according answer.

When I do it through command line it works fine, however when I try to send the answer through my WebSocket, the WebSocket doesn't even start anymore.

Here is my working WebSocket code:

Forgive me for the newb question, but I am confused and obviously not understanding the fundamentals or explanations of how to use a Websocket server hosted over HTTPS. Everything I find online leads me to have more questions than answers.

I have a Websocket server hosted on my HTTPS website using Java code.

This is my WebsocketServer.java file:

I have a task, but I can't seem to get it done. I've created a very simple WebRTC stream on a Raspberry Pi which will function as a videochat-camera. With ionic I made a simple mobile application which can display my WebRTC stream when the phone is connected to the same network. This all works.

So right now I have my own local stream which shows on my app. I now want to be able to broadcast this stream from my phone to a live server, so other people can spectate it.

I know how to create a NodeJS server which deploys my webcam with the 'getUserMedia' function. But I want to 'push' my WebRTC stream to a live server so I can retrieve a public URL for it.

Is there a way to push my local Websocket to a live environment? I'm using a local RTCPeerConnection to create a MediaStream object

With ajax requests it can be done with this code:

I have a websocket implementation using redis messaging operation on webflux. And what it does is it listens to topic and returns the values via websocket endpoint.

The problem I have is each time a user sends a message via websocket to the endpoint it seems a brand new redis subscription is made, resulting in the accumulation of subscribers on the redis message topic and the websocket responses are increased with the number of redis topic message subscribtions as well (example user sends 3 messages, redis topic subscriptions are increased to three, websocket connection responses three times).

Would like to know if there is a way to reuse the same subscription to the messaging topic so it would prevent multiple redis topic subscriptions.

The code I use is as follows:
