Recently, I was trying to check the Alexa rank of a website. But unfortunately, the alexa.com website kept loading for a very very long time. In the end, it just displayed a broken web page.
After some tries, I decided to check the Chrome DevTools for any hints about the issue. In the console window, I saw a weird error message Failed to load resource: net::ERR_HTTP2_PING_FAILED.
Have a look at this error in the below screenshot.
It seems like Amazon's Alexa.com website is unable to connect with the requested website. But, now the question is why would they even try to ping it? Isn't they should have competitive analysis data on their own server?
Or did I misunderstood something?
Do you know what this error code is all about?
