bird test:

inline bird test: ✔
thumbnail bird test: ✖

It looks like someone's gotta update the file "_macros.html.twig" line 63 & 64

<img src="{{ submission.image|imagine_filter('submission_thumbnail_1x') }}"
srcset="{{ submission.image|imagine_filter('submission_thumbnail_2x') }} 2x"

to

<img src="{{ submission.image|imagine_filter('submission_thumbnail_1x')|split('://')[1] }}"
srcset="{{ submission.image|imagine_filter('submission_thumbnail_2x')|split('://')[1] }} 2x"

that would be my best guess.

I mean ideally imagine_filter would return https instead of http, but idk how to mess with imagine_filter

@twovests: does router.request_context.host mean anything to you?
