suggestion: Use a more robust line-splitting strategy for different newline conventions.

Splitting only on "\r\n" assumes Windows line endings. If the list is served with Unix-style "\n" only, you’ll get a single, newline-containing entry and filter(Boolean) won’t fix it. Using something like text.split(/\r?\n/).filter(Boolean) will correctly handle both CRLF and LF cases.

Suggested change
const text = response.data;
const proxyUrls = text.split('\r\n');
const proxyUrls = text.split('\r\n').filter(Boolean);
const text = response.data;
const proxyUrls = text.split(/\r?\n/).filter(Boolean);

const rand = Math.floor(Math.random() * Math.floor(proxyUrls.length));
const proxyUrl = 'http://' + proxyUrls[rand];
let proxyUrl = proxyUrls[rand];

issue: Handle the case where the filtered proxy list is empty before picking a random entry.

With .filter(Boolean), proxyUrls can now be an empty array (e.g., blank/whitespace response). In that case Math.random() * 0 produces NaN, so proxyUrls[rand] is undefined and gets passed to makeProxyAgent. Please add a guard for proxyUrls.length === 0 and either skip proxy usage or log and fall back before computing rand.

// Si la línea ya tiene protocolo, úsala tal cual. Si no, anteponer el protocolo configurado
if (!/^\w+:\/\//.test(proxyUrl)) {
const proto = this.localProxy?.protocol?.replace(':', '') || 'http';
proxyUrl = `${proto}://${proxyUrl}`;

suggestion: Protocol normalization may produce malformed URLs if the configured protocol includes ://.

If this.localProxy.protocol is set to values like 'http://' or 'http://:', using .replace(':', '') leaves proto as 'http//', yielding URLs like 'http///host:port'. Consider normalizing with something like protocol.replace(/:.*$/, ''), stripping :// explicitly, or enforcing a punctuation-free protocol value at config load time.

Suggested change
let proxyUrl = proxyUrls[rand];
// Si la línea ya tiene protocolo, úsala tal cual. Si no, anteponer el protocolo configurado
if (!/^\w+:\/\//.test(proxyUrl)) {
const proto = this.localProxy?.protocol?.replace(':', '') || 'http';
proxyUrl = `${proto}://${proxyUrl}`;
}
let proxyUrl = proxyUrls[rand];
// Si la línea ya tiene protocolo, úsala tal cual. Si no, anteponer el protocolo configurado
if (!/^\w+:\/\//.test(proxyUrl)) {
const rawProtocol = this.localProxy?.protocol?.trim();
const proto = rawProtocol ? rawProtocol.replace(/:.*$/, '') : 'http';
proxyUrl = `${proto}://${proxyUrl}`;
}

options = { agent: makeProxyAgent(proxyUrl), fetchAgent: makeProxyAgentUndici(proxyUrl) };
} catch {
this.localProxy.enabled = false;
