Puppeteer browser hanged on newPage() on Web App Service (Linux with Node 14)

Question

I have published a node.js to Web App Service (Linux with Node 14) that using puppeteer browser to download pdf.
Originally, I used await puppeteer.launch({ headless: true }); (Code is below) but encountered chromium problem.
Then I use await puppeteer.connect({ browserWSEndpoint: 'wss://chrome.browserless.io/' }).
It works in the beginning but hanged on browser.newPage() after idle and no new trace awhile.
I have tried to turn on the Always on option in Configuration but still no luck.

Are there any clues to solve this problem?
Thanks!

@KristieChan-0030 we are sorry to hear you're encountering this issue.

Could you please check the diagnose and solve blade of your web app? From there, click "availability and performance issues" and then "http server errors"

Can you share if there are any http errors and their status and sub status code?

We look forward to your reply.
