Hi,

I have setup cachet with and https APP_URL, trying emails to see how things work before I can properly configure cachet.

I'me getting verification emails with links like : http://localhost/subscribe/verify/9PSWuCke3Vb7V5Sz9mSANnti5EQehImVWlxZ1GdKqq?signature=64b040a19be7fdcc9f923c601c25fcd4f8e878d39d178118969e8617614a8e4c

Is this related to https://github.com/CachetHQ/Cachet/issues/3952 ?
