Websocket server Failed to read header byte (socket FD invalid)
Posted: Sun Jan 08, 2023 11:44 am
I'm trying to publish json data to all connected clients from my ESP32 board.
When I open the server page from Firefox, I see the following logs:
And the corresponding logs on the ESP side:
So only one HTTP client is opened, and WS client (descriptor) is closed immediately.
There is a line in the logs
and I don't know how to fix it.
The full project code is here: https://github.com/dizcza/ws_echo_server
In the end, I want to see how the random numbers are updated on the page each second without reloading the page. The HTLM file is in the repo as well: https://github.com/dizcza/ws_echo_serve ... /root.html
----
The issue is somewhat similar to viewtopic.php?f=13&t=16501&start=10 in a way that Firefox opens two websockets per connection if I'm not mistaken. But the discussion in the pointed link eventually drifted to another issue and the error was not solved for browsers. I need browsers to work with the ESP webserver.
When I open the server page from Firefox, I see the following logs:
