Thanks for sending that @missilic
I see a few issues that might be occurring with your site.
First for the issue at hand, the cURL 28
error is common and usually temporary but if it is persistent then you need your hosting provider to investigate the issue with regards to the cURL library installed on the server. They also need to make sure that they are not blocking outgoing connections to our server IP address range 69.46.36.0 to 69.46.36.32.
You may be able to start scans remotely. Navigate to Tools > Diagnostics > Debugging > Start All Scans Remotely and enable that. Return to your scan page and CANCEL the current scan and then start a NEW scan.
I also see most of your cron jobs haven’t run since December 9th which will also cause issues. I would also have your host see why these aren’t running.
Let me know what you find!
Thanks!
