selenium webdriver can't connect to devtools websocket

[NathanFRuiz]

when trying get selenium library to connect to the devtools web socket i'm getting the following error when proxying through ggr, is the devtools websocket savailable out of the box or does it demand extra settings?

Unhandled exception. OpenQA.Selenium.WebDriverException: Unexpected error creating WebSocket DevTools session.
 ---> System.Net.WebSockets.WebSocketException (0x80004005): The server returned status code '400' when status code '101' was expected.

I've tried to add the following to the quota file but had no luck

<host name="{host_ip}" port="4444" vnc="ws://{host_ip}:4444/vnc" devtools="ws://{host_ip}:4444/devtools" count="1"/>

@NathanFRuiz we never said that Selenium 4 devtools is supported in Selenoid \ Ggr.

Got it, I was lead to think that by this session on documentation:

But we can work around it somehow, thanks for your time.

@NathanFRuiz yes, this feature works. But Selenium 4 also requires processing additional capabilities and this is not currently implemented in Selenoid \ Ggr.
