SSL certificates issued for too long fail to work with Chrome

[jimtaylor123]

Describe the bug
Magic lamp creates ssl certificates for longer than 39 months. Chrome does not trust ssl certificates issued for longer than this period. This means the ssl cert does not work as expected and the page is insecure/not trusted.

To Reproduce

1. Set up magic lamp
2. Install the generated ssl cert (eg on mac using keychain)
3. Go to the intended URL

Expected behavior
To be able to visit the intended development url on a secure connection.
