Puppeteer

I was unable to access any webpages using the Crawlera proxy. 

I used the code as shown on the support website (https://support.scrapinghub.com/support/solutions/articles/22000220800-using-crawlera-with-puppeteer) and just tried to load the Yahoo website. The error message that I got is shown in the attached screenshot.

I tried with multiple different websites, and it all failed.

Please advise.
