Website proof won't update

I accidentally moved my keybase.txt file away from my root folder on my website, but I fixed it when I got a notification from Keybase. Now when I click to verify the proof I get this popup:

Ok, we're checking...
We failed to retry your proof.

Start by reproducing the website proof verification after restoring keybase.txt to the site's root folder, using the reported “We failed to retry your proof” popup as the symptom. Trace the website's proof retry flow and determine why the corrected proof is not accepted; done means verification succeeds after the file is restored.
