Table not accessible when using data.headers

[niutech]

This YQL query used to work fine until the end of November:
use "https://raw.githubusercontent.com/yql/yql-tables/master/data/data.headers.xml" as headers; select * from headers where url="https://example.org"
but now it raises the error: {"error":{"lang":"en-US","description":"Table not accessible"}}

What is the issue? Could you please fix it?
