https://developers.google.com/speed/pagespeed/insights/?hl=ja&url=https%3A%2F%2Fwww.wisebk.com%2F Our web site got an error Sometimes it is ERROR TIMEOUT , sometimes ACCESS DENIED error. Does anybody know why this website got an error on page speed insight?
https://www.wisebk.com/ This is wordpress website.
Because your site doesn't respond fast enough, it took nearly 30 seconds to send the first byte (for your server to respond).
This could be a regional thing as Page Speed Insights servers are in the US (and I am in UK) so perhaps read this answer on how to run Lighthouse locally (the engine behind Page Speed Insights) and see if that works (or initially just run Lighthouse in Google Chrome Developer Tools).
Other than that it is a symptom of an overloaded server or something that is wrong with your theme (perhaps trying to dynamically build the page from the database and there is a very long running database query), could be hundreds of things but that is the reason Page Speed Insights isn't working for you.
