keybase.io verification of gist post error

Here is the email I get:

Hi, cryptodan, your attempted github identity proof of @cryptodan never succeeded. We've been checking it repeatedly, and from our perspective, it's either (a) not there, or (b) not posted precisely.

If you think there's a bug, please post an issue on github. Include the link to your proof.

And here is your profile, in case you'd like to try again: https://keybase.io/cryptodan.
You may also prove yourself with the keybase command line app.

Thanks! -Keybase

Yet I have the information posted in a public gist with the proper naming.

Here is my keybase.md file: https://gist.github.com/cryptodan/3f1ec1fedbfff44f8214d9558fb99875

Start by reproducing the GitHub identity verification for the public gist linked in the issue and compare its naming and contents with the proof format Keybase expects. Done means the linked gist is recognized successfully, or the issue documents a confirmed verification defect with reproducible details.
