Error: REST API generated an error, Your website could not perform the loopback request for one of the hosting the same website, how to fix?
There is one and the same site on two hosts, one test, and another in which the site should work
so on the test:
so on the second:
php version is different, but they were the same at the time the error occurred, I updated in an attempt to remove the error
In PageSpeed Insights, the second gives this error:
Lighthouse returned error: FAILED_DOCUMENT_REQUEST. Failed to load page. Make sure that URL entered correctly and the server responds to all requests. Read more: net::ERR_TIMED_OUT.Close
I don't know if, but it's only when you inspect an https version of the site, if I enter http, there is no error.
And a test site without a certificate at all at the moment.
The second site certificate from Let's Encrypt received via the hosting panel, and the second site worked fine for 15 days,and now here such trouble
Can you please tell what could it be?
I suspect that this is problem with hosting
