That's weird. If you can come up with a small reproducible example, I can have a look.

We have a test here: https://github.com/xvrh/puppeteer-dart/blob/master/test/connect_on_web_test.dart to show how to connect to puppeteer from a web page.

Recently we hit a bug with that test: starting from Chrome 111, we cannot make a direct websocket connection from the webpage to the Chrome devtools. The server refuses the connection or something. I had to add a proxy in-between to make the bridge. See the comment in the code.

Actually, I just found a solution here: https://groups.google.com/g/chromedriver-users/c/xL5-13_qGaA

We can launch puppeteer with the --remote-allow-origins=* flag and it works for even in chrome >=111

ie.

var browser = await puppeteer.launch(args: ['--remote-allow-origins=*']);
