Resolved port 443: Connection refused?

[Space Monkey]

In WP I got 2 critical issues. Below are the messages:

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://alternus.nl/wp-json/wp/v2/types/post?context=edit
REST API Response: (http_request_failed) cURL error 7: Failed to connect to alternus.nl port 443: Connection refused

Loopback requests are used to run scheduled events, and are also used by the built-in editors for themes and plugins to verify code stability.

The loopback request to your site failed, this means features relying on them are not currently working as expected.
Error: cURL error 7: Failed to connect to alternus.nl port 443: Connection refused (http_request_failed)

This handled by Plesk?

Hello @Space Monkey

Did you get a solution for this critical error or?

I fixed that problem by adding the current ip to /etc/hosts, as explained here [Solved] cURL error 7: Failed to connect to domain.com port 443: Connection refused Vestacp - JustWebU ... I don't know why Plesk don't add this automatically

I don't know why Plesk don't add this automatically

Because it is a basic operating system setting. Plesk does not touch your nic settings. On many systems, /etc/hosts is maintained automatically by a system service, too.
