XML-RPC posting problem for wordpress blogs

There appears to be a major problem with XML-RPC posting for wordpress blogs for the last few days

404 error with XMLRPC for wordpress 4.7.5
Have been getting the following remote posting error with wordpress blogs
An error occured while uploading the post
Error transferring post to the server
HTTP Error code : 404
NOT FOUND: The server has not found anything matching the requested URL (Uniform Resource Locator)

Post error – -32300:transport error – HTTP status code was not 200

Is any one else facing the same problem.
