openssl error when adding url

[derixithy]

I get the following error when i try to add some sites (not all).

Warning: DOMDocument::loadHTMLFile(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed in /path/to/unmark/application/controllers/Marks.php on line 54

Warning: DOMDocument::loadHTMLFile(): Failed to enable crypto in /path/to/unmark/application/controllers/Marks.php on line 54

Warning: DOMDocument::loadHTMLFile(https://fedoramagazine.org/install-atom-fedora/): failed to open stream: operation failed in /path/to/unmark/link/application/controllers/Marks.php on line 54
[BACK](https://link.usershare.nl/) There was an error adding the mark.

Most likely the URL is invalid or the web site isn't currently available.

There is no way to add the site manually except for the bookmarklet.
