            Not able to connect to websocket using Nginx and Uvicorn
            Asked 2022-Mar-26 at 10:20

            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:

            The websocket server is a daemon and all cleanup tasks are the responsibility of the developer

            Use

            Browsers do not support headers for websockets, therefore the bearer token has to be added as query string parameter. We hit the maximum length for URLs due to the length of our bearer token. We could shorten our token or use a reference token, see also: https://github.com/aspnet/SignalR/issues/1266

            .NET 6.0: new Blazor project throws Websocket error
            Asked 2022-Feb-26 at 12:07

            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!

            There is no problem with your websocket route. Could you please share how you are triggering this route? Websocket is a different protocol and I'm suspecting that you are using a HTTP client to test websocket. For example in Postman:

            Postman New Screen

            HTTP requests are different than websocket requests. So, you should use appropriate client to test websocket.

            Keep it easy.
            Certs inside your application are complex - they are hard to manage and you will get problems to run your application in a modern cloud environment (start new environments, renew certs, scale your application, ...).

            Simple conclusion: Dont implement any certs.

            How-to get encrypted connections?

            As Mike already pointed out in the comments: WebSockets are just upgraded HTTP(S) connections. A normal webserver (nginx, apache) takes care about the certs. It can be done in kubernetes (as ingress-controller) or with a "bare-metal" webserver.
            Both of them should act as a reverse-proxy. This means: Your java-application doesn't know anything about certs. It has just unencrypted connections - like in your code on port 6868.
            But the client will not use this port. 6868 is only internally reachable.

            The client will call your reverse-proxy at the normal HTTPS port (=443). The reverse-proxy will forward the connection to your java-application.

            Push local WebRTC stream to a NodeJS server in the cloud

            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?

            It's not straightforward because you need more than vanilla webrtc (which is peer-to-peer). What you want is an SFU. Take a look at mediasoup.

            To realize why this is needed think about how the webrtc connection is established in your current app. It's a negotiation between two parties (facilitated by a signaling server). In order to turn this into a multi-cast setup you will need a proxy of sorts that then establishes separate peer-to-peer connections to all senders and receivers.

            Asked 2021-Oct-18 at 14:57

            I would like to know how many TCP connections are created when WebSocket call is made from browser to apache http server to backend web service?

            Does it create a separate TCP connection from the browser to apache http server and from apache to the web service?

            ANSWER

            Answered 2021-Oct-18 at 14:57

            When Apache is proxying websockets, there is 1 TCP connection between the client and Apache and 1 TCP connection between Apache and the backend.

            Apache watches both connections for activity and forwards read from one onto the other.

            This is the only way it can be in a layer 7 (Application Layer, HTTP) proxy. Something tunnelling at a much lower layer, like a NAT device or MAC forwarding IP sprayer could tunnel a single connection -- but not on the basis of anything higher up in the stack like headers.

            The 2nd connection is observable with netstat.

            The 2nd connection is opened when mod_proxy_wstunnel calls ap_proxy_connect_to_backend() which calls apr_socket_create() which calls the portable socket() routine. When recent releases of mod_proxy_http handle this tunneling automatically, simialr flow through ap_proxy_acquire_connection.
