I need a little server (OBJ-C, iPad, XCode) using ssl negociations and exchanges when a client tries to connect.
Is someone knows how to do this or have a little example?
Thanks to all

I am trying to build a system using Socket.io and YARP. Yarp is functioning has a Reverse Proxy to all my Services.
When trying establish a connection to my socket.io service, through yarp, I am getting connection_error:
I noticed there are proper configurations used in other Reversed Proxy solutions that are well documented in Socket.io website:
https://socket.io/docs/v4/reverse-proxy/
However, I can't "translate" what they are doing to YARP. Does anyone know if this is possible?
Thanks in advance
I guess stackoverflow was my rubberduck this time...
I checked in postman the request that was being made through my Yarp Server and turns out it wasn't even hitting the correct path. For yarp to connect to a socket.io server you have to use this kind of path in your configuration file:
It seems that a sokcetio request uses it's own path, so you have to make your reverse proxy match the beggining "socket.io/"
i'm trying to create a realtime app with laravel-websockets package, i followed the steps in laravel documents and also the laravel-websockets package and i did all the thing exact the same as docs, but whenever i try to send an event through the channel i receive this error in the browser console:
Firefox can’t establish a connection to the server at wss://127.0.0.1/app/myKey?protocol=7&client=js&version=6.0.3&flash=false.
does any body know how can i solve this error?
i found a solution for my case here:
https://github.com/beyondcode/laravel-websockets/issues/382#issuecomment-631569344
try this out, i hope it works for you too.
I think this is an SSL related problem. Here you are using wss:// protocol on the localhost. I would suggest you use ws:// protocol instead of wss://.
Hope that this will work.
I’m posting Https request to our server(the server is in America and I am in China), the certificate is configured right, but now I have some issues:
In network 4G, everything goes right. When in Wifi, the request always goes to "Time out". I'm using AFNetworking, someone suggests related to SNI ? Anyone ever meet this issue? I need your help.
Thanks in advance.
Websockets applications are not working on my network.
However, websites like http://www.websocket.org/echo.html and http://websocketstest.com/ tell me that everything is working.
When trying an application of my own, it appears the handshake goes through successfully, but after that none of the messages get across.
Any ideas what could be the reason for this? An explanation would be much appreciated.
I'm trying to write a server for a webSocket connection. I've read the spec (76, not 75) carefully. I'm using minefield as the browser.
When I try to create a WebSocket from javascript in the browser:
var ws = new WebSocket("ws://localhost:8766/hoho");
The browser responds with
"Firefox can't establish a connection to the server at ws://localhost:8766/hoho."
My server is getting a valid client handshake request, it sends back the response and then boom.
I've run every example handshake example I can find through my server and I match the given responses exactly in every instance. I'm pretty confident that the return byte stream is correct. I don't need help debugging my code, it's doing what I mean it to do. I need help debugging my use of the handshake protocol since when I give minefield what I think is a correct response it laughs at me.
My question is this: How can I debug this thing? I can think of two possibilities.
Is there any way to get minefield to tell me WHY it's rejecting my handshake?
Is there a working, public, webSocket server service on the web? If there is, I can proxy it, watch the byte streams in both direction and figure out where mine is different.
Does anyone have any ideas in these directions or any other ideas?
Thanks for any help.
I'm in the process of debugging a similar situation, and the tool I'm relying on most is netcat, with some additional use of openssl. Shut down your websocket server and run nc -l 8766. That lets you record exactly what headers are being sent. Turn the websocket server back on and use nc 8766 to paste in those same headers and see the result. openssl s_client -connect localhost:443 will let you make the request with ssl, if that is in your mix.
From there, make sure the responses conform completely to the websocket handshake protocol. For instance, my problem right now is that my responses have Connection: close, which is no good.
About the 2nd possibility.
Yes, there is a websocket server out there.

hope this helps
Added: Echo socket server at: http://www.websocket.org/echo.html
Here's a jsfiddle that I made from http://www.websocket.org echo websocket server which works in Chrome but not in Firefox 6: http://jsfiddle.net/awDLc/
It is adjusted to use MozWebSocket rather than WebSocket, but perhaps that isn't enough?
