WebSocket is closed before the connection is established
I’ve got an issue with an app and I’ve no idea of how to troubleshoot it. I’m hoping someone here might have seen something similar.
I pushed out an update to a test app, and now when i browse to it, it’s stuck in a cycle trying to connect to the web socket. The static content is displayed, the browser tries to connect to the web socket, it times out and repeats the cycle.
I have seen this in the development environment too very intermittently (like twice). I thought it might be something to do with the code reloader, because as soon as I switched that off in dev, the problem went away.
Any ideas about where to start looking?
Also, it seems confined to a browser session. ie, I can browse to the same app in a different browser and it works fine… So with that in mind, I cleared cookies on the failing instance, crossed my fingers… but still no good.

This is the third report I have seen with Brave hanging in the 101 websocket upgrade. Unfortunately it doesn’t appear to be anything on our side and by all things I’ve seen the bits never make it to the server. One person had it happen only when the adguard extension was enabled, but disabling didn’t fix it until they restarted Brave. Both previous reports I’ve seen restarting Brave fixed it, but this looks like some obscure issues squarely on Brave’s side. I have wondered if we are attempting to connect too aggressively for brave, but it is a total guess. If you are able to reliably recreate, you could try instantiating the liveSocket and liveSocket.connect inside a window.addEventListender("DOMContentLoaded", ...)

from a very quick look it seems like Brave proxies websocket when the shield is “up”.. through this code: brave-core/browser/net/brave_proxying_web_socket.cc at master · brave/brave-core · GitHub (and probably else where for the 101 upgrade - NOT a C expert)
there was a recent commit to that file fixing a bug 15715: Properly shutdown our websocket proxy. · brave/brave-core@79783d3 · GitHub, slated for next major brave version (1.26) but totally unknown if it fixes anything related to this issue..
but does sound plausible that some issue exist with brave, especially when using the shield ws proxy.. maybe it can be sporadically reproduced running 100-1k tests with wallaby/chromedriver?
