The “CURL ERROR 7 Failed to connect to Permission denied” is thrown if the curl request is blocked by some firewall or similar thing.
You’ll get this error when your PHP settings or your firewall blocks requests to our server wp-staging.com.
You can also get the error if the “cURL” and “OpenSSL” libraries are out of date on your web server. To fix this ask your host to update cURL and OpenSSL on your server.
If you still get this error and do not know how to solve it to activate your WP Staging Pro license get in contact with us and we offer you a solution for this.
