Template takes too long to boot, throws R10 error

[afry-siam]

This starter kit runs beautifully locally, but at least for me, the build + startup time on Heroku is exceeding 60 seconds, which causes Heroku to throw the following error:

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

To get around this issue, you can increase the boot time via Heroku's support page: https://tools.heroku.support/limits/boot_timeout

Increasing the build time limit to 120 seconds worked for me.
