2 Critical issues - WordPress Site Health

[epiz-aroy]

I have found 2 Critical issues of my WordPress website.

Link: www.haldibarimazarsharif.com

1. 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 60: Peer’s Certificate issuer is not recognized.

2. Your site could not complete a loopback request

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 encountered: (0) cURL error 60: Peer’s Certificate issuer is not recognized.

How can I solve this issues? Please help me.

The two critical issues actually appear to be caused by the same error, which is that your WordPress installation is unable to verify the SSL certificate of your website.

I was going to say that this is probably caused by a known issue of our SSL management tools, but then I saw your domain is using Cloudflare. Was your domain using Cloudflare when you first got this error or is it something you’ve tried later on?

@Admin I have faced this issue after few days of using cludflare.
