Has this only been occurring after enabling CFS? Show us your CFS rules.

Unless you have DPI-SSL setup properly you will get 'Connection Reset' when you browse to 'blocked' HTTPS page. 'Big' sites usually use content delivery networks (CDNs), try identifying the CDN and adding them to the URI allow list.
