Hi, I would discard a problem on client side( client machine or browser)
I just tested with client on a different machine (firefox and chromium) and it didn’t work
I think is a problem on the server machine, but I don’t know where it could be

You are not really making it easy to help you. Your case lacks so much vital information. You should REALLY put this vital information into first post.
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
Reading this you are probably missing something all these projects need. Lot of example and default project needs PostgreSQL to be installed. Do you have it installed on computer that fails with same passwords etc? You can also create new LiveView project that doesn’t need PostgreSQL using some parameters that I can’t remember.

I know there are something missing, but I don’t know what, or how to investigate to detected what is wrong in this computer
I’m trying to give you proper information about the problem, and also I’m trying to avoid not valid datas
For example, about postgresql, I ran projects with --no-ecto and no postgresql or any other database dependency at all
I run on different machines, non of them with postgresql installed (no server, no cli)
In all machines work, excepting the mysterious one
I will develop a minimal project on a computer that works, I will download on the machine that fails, and I will share this project with you. I don’t think it will be help a lot, but I could be wrong

Do elixir --version and check that both Erlang/OTP and Elixir versions match between the computers.

Here you have a very simple project with an example that works in all computers excepting one
https://github.com/jleahred/testing
It has been created with mix phx.new mini_live_view --no-ecto, and I modified just the router.ex to put
live "/", CounterLive
And two very small files for CounterLive

The machine with the problem…
> elixir --version
Erlang/OTP 24 [erts-12.1.5] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [jit]
Elixir 1.13.0 (compiled with Erlang/OTP 24)
I tested this with Elixir 1.12.x and Elixir 1.13 on four computers. Only one of them fails, no matter Elixir 1.12.x or Elixir 1.13.0

This is one machine that works normally
❯ elixir --version
Erlang/OTP 24 [erts-12.1.5] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [jit]
Elixir 1.13.0 (compiled with Erlang/OTP 24)
This is in the machine that fails
> elixir --version
Erlang/OTP 24 [erts-12.1.5] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [jit]
Elixir 1.13.0 (compiled with Erlang/OTP 24)
The machine that works, is a fresh installation (few days ago)
The other one, is a rolling release. On this machine, everything was working fine with phoenix/liveview till some days ago
I have no clue of what happened 
And I didn’t detect any other fail on this machine. Everything looks working fine the only problem I detected, is this with phoenix/liveview

You don’t happen to have anything else running in port 4000 in that machine? Try running Phoenix in different port than default 4000 and see what happens.
