This should resolve your connection to any website you may have previously had issue connecting to. If you’re still having problems, it could be that the website is currently experiencing some internal issues. You may want to find their support channels or social media accounts to determine whether the issue may be on their side. If you know that the website you are connecting to is safe, you can choose to continue to the website by using Google Chrome. When visiting the website, choose to ignore the security risk by clicking ‘advanced options’ and clicking proceed anyway.
