Puppeteer hangs on content() call when using stealth plugin + socks proxy

Hi,

I’m using puppeteer stealth plugin.

puppeteer.use(require('puppeteer-extra-plugin-stealth')());

My pupeeter calls are using socks proxy while starting chrome browser using following argument.

--proxy-server=socks5://IP:PORT

After doing visit to cloudflare protected page the script using stealth plugin is hanging on page.content() call:

 let response = await page.goto(this.task.url, {waitUntil: 'domcontentloaded', timeout: 45000});
        this.logger.info("VISIT 2");

        let content = await page.content(); //HANGS HERE. When disabling stealth plugin, it works just fine. 
        this.logger.info("VISIT 3"); //will not be printed

Whenever i disable stealth-plugin, everything is working just fine and no longer hangs on content() call.

If i start the script with visible chrome window, everything is working fine too.

Problem is when we’re using headless mode, visiting cloudflare protected website (not sure if important) and using a proxy. Disabling stealth plugin resolves all issue or disabling proxy.

What might be the cause?

I will add more info when i will be at the machine. Yes, the proxy is relevant.

Works (headless mode):

• Plugin + no S5 proxy
• No plugin + S5 proxy

Does not work (headless mode):

• Plugin + S5 proxy

Unfortunately the debug output doesn’t mention anything interesting 😕

Without the full code incl. socks proxy I won’t be able to help here. If you’re able to make a small self-containted script showing the issue and provide socks proxy credentials as well you can send me those in a PM in our chat.
