WARN: No Metatags Found


#1

Description of issue:
The card validator seems to not be receiving the metatags from my site. I have all the twitter metatags plus the Open Graph ones.
I can confirm that my site works on the facebook debugger, and the curling with curl -v -A Twitterbot http://www.echoic.space returns the expected tags.

My site is hosted on Heroku, if that means anything.

URL affected (must be public):

Troubleshooting steps attempted [note that we will not prioritise posts unless there is evidence of following the troubleshooting guides]:
All of them, except the wordpress ones because I am not on wordpress.
