See #2127. the line seems very long though.
Note: this was previously commited as #2184 but as there were two mistakes
and one other thing which could be improved I decided to make a hard reset.
Apologize if it caused inconvenience.
Respect changed HSTS epoch time of 180 days.
(DROWN output is changed too as the certificated changed but doesn't matter
as the travis check filters that)
