Routing or async issue: when routing from homepage to view certificates [production only]

[soulofamachine]

This issue occurred in production quite suddenly... without any changes to the repo...

To reproduce this:

1. go to forevermore.io
2. click to view one of the vows
3. Error:
   Mixed Content: The page at 'https://www.forevermore.io/' was loaded over HTTPS, but requested an insecure favicon 'http://forevermore.io/static/Logo.png'. This request has been blocked; the content must be served over HTTPS.
4. If you hard refresh, everything is fine
