Keybase proof on reddit failing for a while

Out of the blue, my keybase proof (which had been live for years) started failing.

So I keep re-posting it and retrying.

Here is the link:

https://www.reddit.com/r/KeybaseProofs/comments/1d5psaq/my_keybase_proof_redditkayvansylvan/?

Start by checking the linked Reddit proof and reproducing the reported failure through the Keybase client. Trace the proof-verification entry point and compare the current result with the posted proof; done means the cause is identified and verification succeeds again or the external failure is documented.
