Maxim I apologise if I've offended you or not understood something you
wrote. My methodology was as follows:
- Install nginx
- Enable ssl
- Run the SSL Labs scan and a current version of Chrome
- Provide a patch that fixes the errors reported by those tools
Do you believe the provided SSL Labs report or Chrome is in error, or that
something is wrong with the testing methodology above?
