The REST API is one way that WordPress and other applications communicate with the server. For example, the block editor screen relies on the REST API to display and save your posts and pages.

When testing the REST API, an error was encountered:

REST API Endpoint: https://mydomain.com/index.php?rest_route=/wp/v2/types/post&context=edit
REST API Response: (http_request_failed) cURL error 28: Operation timed out after 10001 milliseconds with 0 bytes received

all the sites
I had some update and i did it and it went away for an hour than came bak

can someone know about it

allow me to share the solution that I found it has something to do with max_execution_time, while mine was 600 which was causing the issue . I started to think what is the right setup for the the PHP setting.

this is my current PHP setting which I think needs adjustment
what is the proper
max input time ?
max input Vars? [COLOR=rgba(255, 255, 255, 0.87)]

max_execution_time	30	Delete​
max_input_time	300	Delete​
max_input_vars	5000	Delete​
memory_limit	1024M​	Delete​
post_max_size	128M​	Delete​
upload_max_filesize	128M​	Delete​

Api Issue was caused by one single web site that spreads to all the other websites on the server, How I dont know ? anyway find the the exact website that caused all those trouble is very good step.
delete the website or suspend the site release the errors on all the other sites.
Than I deleted the site and reinstall from the back up I am getting a different API errors

REST API Response: (403) Forbidden

At the end eventually I find out that the security plugin of this website has an option to block the Rest API, sounds like I did that in the past by mistake.
Reset the security plugin reinstall with correct setup all good.

also there were some customer rule on cloudFlare WAF for secuirty that was blocking the Pi access which it should not, but it does.
I hope that helps, before doing a bigger unnecessary modification in the entire server
