Explanation

HTTP 412 Precondition Failed status code indicates that one or more preconditions specified in request headers (such as If-Match, If-None-Match, If-Modified-Since, or If-Unmodified-Since) evaluated to false. The server is rejecting the request because the condition required for the request was not met.
