Cache Access Denied

[CH]

`const page = await browser.newPage();

await useProxy(page, 'https://power-fr.tlsext.com:10799');
await page.goto('https://google.com', {
    waitUntil: 'domcontentloaded',
})

`

When I open the page,it shows below wrong message:
Cach Access Denied
The following error was encountered while trying to retrieve the URL: https://google.com/*
Cache Access Denied.
Sorry, you are not currently allowed to request https://google.com/* from this cache until you have authenticated yourself.
