    Hi @dzembak,

    It is not the same issue. From your error message, it indicates the issue with your certificate that your web server is serving. Please contact your hosting company support to fix the certificate of a server for you. You can provide them the Debug: section of the output, it will be clear for them what to do.

    Alternatively, you can disable the SSL verification by adding the custom code. You should not do this unless you have to – it’s compromising your security.

    In case it helps, here’s a tutorial on where and how to add custom codes like that: https://www.wpbeginner.com/plugins/how-to-easily-add-custom-code-in-wordpress-without-breaking-your-site/

    I hope this helps!
