How to fix The REST API is one way WordPress, and other applications, communicate with the server

We are setting DWQA Pro using and getting a Site Health Critical Error:
** The REST API encountered an error **
The REST API is one way WordPress, and other applications, communicate with the server. One example is the block editor screen, which relies on this to display, and save, your posts and pages.
The REST API request failed due to an error.
Error: [] cURL error 28: Operation timed out after 10000 milliseconds with 0 bytes received

I have deactivated all my plugins but nothing. Really without explanation it's a waste of time.
Thanks for the initiative though.

[@ortals]

[@thalesthales.6292]

Was a good intention but I dont have the captcha plugin either .. but tks

[@GospelBlast]

Me too 😂

[@ammnews]

I didnt add that pluginv then how to deactivate it

[@zuhairkhayat2827]

@Shlomo Asaf How to know the plugins that causing the problems ?

[@SaboresdeisraelBr]

@@zuhairkhayat2827 I just disabled plugins till I found the problematic one.
I also deactivated all plugins to see if the problem got solved. This way I could tell that a plugin was causing the problem, then just find the problematic one is a matter of time ;)

What does this problem cause? Nothing.. It is not a big issue to keep the captcha plugin. What am I missing? Yes it says that it is an error in the "site health" section, but it doesn't cause any problems on the website... Or does it? What am I missing here?

[@chicovazquez1296]

waste of time, don't even have that plugin

[@GospelBlast]

@Shlomo Asaf how???

[@GospelBlast]

@Shlomo Asaf okay

[@IceEastwood]

good intention, but you didn't explain why it was causing that, and how did you found out that it was causing trouble. Thumbs down

[@JAYNEDOE_]

Slow video, could have cut half the time by removing the spinning wheel. Also agree with below comments, don't even have that plugin and no explanation as to what is causing this error. Guess I have to keep looking.
