Hi!
I installed recommanded plugin. See what I get:

The site health check shows critical information about your WordPress configuration and items that require your attention.

Critical issue

Your site can not connect to my.yoast.com

You can not activate your premium plugin(s) and receive updates. A common cause for not being able to connect is an out-of-date version of cURL,
software used to connect to other servers. However, your cURL version seems fine. Please talk to your host and, if needed, the Yoast support team to figure out what is broken. Read more about cURL in our knowledge base(Opens in a new browser tab).

Thanks for fast response!
I followed your instructions, step by step.
Still the same problem.
Also any Javascript errors.
Thanks for help!

The same problem that @shayanfp. The optimization for our SEO data couldn’t be completed. On your suggestion I go to Tools/Yoast Test helper, after click on “Reset Indexables tables & migrations” I get notice: “There has been a critical error on your website. Please check your site admin email inbox for instructions.”
I received a mail, that the problem is Yoast Test Helper plugin itself:

Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, Yoast Test Helper.

First, visit your website (https://www.terrasleep.si/) and check for any visible issues. Next, visit the page where the error was caught (https://www.terrasleep.si/wp-admin/admin-post.php) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can’t access your dashboard normally, WordPress now has a special “recovery mode”. This lets you safely login to your dashboard and investigate further.

To keep your site safe, this link will expire in 1 dan. Don’t worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 5.5.3
Current theme: Twenty Twenty (version 1.5)
Current plugin: Yoast Test Helper (version 1.9)
PHP version 7.2.24-0ubuntu0.18.04.7
