404 on .well-known/acme-challenge/

Thanks will try again in 30 minutes… Shortly after I got that initial 500 error I tried again and got a different error

raise errors.MissingNonce(response)
MissingNonce: Server POST response did not include a replay nonce, headers: {'Content-Length': '1488', 'Expires': 'Tue, 10 May 2016 16:57:05 GMT', 'Server': 'nginx', 'Connection': 'close', 'ETag': '"55f255cc-5d0"', 'Pragma': 'no-cache', 'Cache-Control': 'max-age=0, no-cache, no-store', 'Date': 'Tue, 10 May 2016 16:57:05 GMT', 'Content-Type': 'text/html'}`

Perhaps this also do to the partial outage?
