[NghiaTranUIT]

Description

There are at least 2 users, who reported this bug.

It shows 127.0.0.1 (default value) in the Android Setup, and the status bar.

Steps to Reproduce

1. Not sure hot to reproduce it, but it's failed to get the current IPv4

Current Behavior

• Can't get the current IPv4

Expected Behavior

• [ ] Double check the func, to see why Proxyman can't fetch any IPv4
• [ ] Find a better npm package (high download, reliable, ... ) (maybe we can fall back to current library if the new one doesn't work) -> Find in this docs: https://www.electronjs.org/docs/latest/api/session to see if we have any native API to get the IPv4

Maybe we can leverage the os from NodeJS.

const os = require('os');

function getIPv4Address() {
    const networkInterfaces = os.networkInterfaces();
    for (const interfaceDetail of Object.values(networkInterfaces)) {
        // `interfaceDetail` might be undefined if no network is attached to the interface
        if (!interfaceDetail) {
            continue;
        }
        
        for (const detail of interfaceDetail) {
            // Look for an IPv4 address that is not an internal (localhost) address
            if (detail.family === 'IPv4' && !detail.internal) {
                return detail.address;
            }
        }
    }

    // Return undefined or a fallback address if no external IPv4 address was found
    return '127.0.0.1';
}

console.log(getIPv4Address());
