Have you tried 127.0.0.1 instead of localhost? On my Windows computers localhost has problems with WebSocket connections on Chrome. WebSocket connections take very long time to connect. But 127.0.0.1 works fine.

Yep, I tried with 127.0.0.1 and the IP address (after changing configuration to allow external connections on dev)
Nothing working
I’m trying to debug as quatermain proposed.
Thanks

When I run
liveSocket.enableDebug()
in the machine that fails… I got an error
liveSocket.enableDebug() is not a function
But running on a machine that works, I can see on console the debug info and trafic

Are sure you are running 100% identical code in both machines? Because liveSocket is a variable that JavaScript related to LiveView should create. If it’s not available then it feels to me that something is wrong with the JavaScript code or maybe the code itself is not run at all.

Exactly. Can you check source code from browser debug tool? Because it looks like your JS is not executed on that machine. Which browser do you use? Do you use some extensions? Ad blockers? What about log from your terminal/console when you start Phoenix app, usually webpack “compile” your assets and generate main js file. What do you use for assets? esbuild? node? webpack?

Yep, I tested with my code, and with examples from Chris McCord downloaded from github and compiled on my machine
I downloaded my on code from repository in different folders and machines
I created new projects, and works on all machines, excepting this one 
Everything works fine except in one machine. In that machine, nothing related with liveview works
I’m going to test a client from a different machine against the server. Then I will know if the problem is on server side, or client side (I bet is on server side, elixir/phoenix)

I could, I could create a very simple application that fails on this computer, but… I don’t think it will help
I have problems with my code, with a new project, with code from examples from Chris MacCord on github. And only fails on one machine. The same code in 3 different machines, works perfectly

The program fails on chromium and firefox
No addblockers configured
I putted a breakpoint on socket.js on
export default class Socket {
constructor(endPoint...
this...
I ran step by step, no errors, no exceptions, no messages on console…
After running the constructor, I tested on console the activation of debug
liveSocket.enableDebug()
It appears on code completion but the execuion gives…
VM630:1 Uncaught TypeError: liveSocket.enableDebug is not a function
at <anonymous>:1:12
