How to fix Playwright proxy error?

Question

Node.js

I was tormented for a long time, I could not correct the error. Proxy data changed many times.

The code:

const browser = await firefox.launch({
      product: 'firefox',
      ignoreHTTPSErrors: true, 
      proxy: {
        server: `http://${proxy[i].ip}:${proxy[i].port}/`,
        user: username,
        password: password
      }
    });

Console:

(node:61465) UnhandledPromiseRejectionWarning: page.goto: net::ERR_TUNNEL_CONNECTION_FAILED at http://2ip.ru
=========================== logs ===========================
navigating to "http://2ip.ru", waiting until "load"
============================================================
Note: use DEBUG=pw:api environment variable to capture Playwright logs.
