I am currently trying to do web scraping with node and puppeteer headless chrome. I use a voting website, where you can vote only 1time/hour, and I am trying to vote more (like 10times/hour for exemple). For this purpose I use different IP adresses and different User Agent. But, the problem is, when I switch IP it doesn't seems to work( I cannot put an other vote) and when I check my IP on (on some website like https://ipcost.com/) I see my real Ip address.

Here is the code I use to achieve this:

const chromeOptions = {
    headless:false,
    defaultViewport: null,
    args: [
        '--disable-features=IsolateOrigins,site-per-process',
        '--flag-switches-begin --disable-site-isolation-trials --flag-switches-end',
        '--disable-features=UserAgentClientHint',
        `--proxy-server=http=user::passwordx@ip:port`
      ]
(async() => {
const browser = await puppeteer.launch(chromeOptions);
....
})()
};

This is the first time I am working on web scraping and I use proxy like that. I wasn't able to find any answer to my question, I think I am missing something or I am doing something wrong.

Thanks in advance for your help
