Source dataflow is failing with error - "2200 - The remote server returned an error: (404) Not Found."

The source dataflow is failing with the above error. Some one kindly give some information about this. 
I am seeing this error for the first time.

@JettyRo If this is still an issue, do you have more details about the dataflow? What source is it ingesting from? Are you sure the source can be accessed?
