I configured a Data Extract (Data Extension Extract) and a File Transfer (Safe House to External FTP which is also an SFMC FTP ).
Unfortunately, File Transfer fails without giving a proper error.
ERROR: An undefined error occurred. Contact your account representative if the error persists.
Salesforce Support is asking me to whitelist Stack 1 IP Address on my Internal Network when the operation is done within SFMC Servers. I have ask them to escalate this to Tier 2 support.
Have you come across this issue in the past? What have you done to resolve this issue?

Marketing Cloud Tier 2 told me that the exception at backend is "FTPOutputProtocol: ReadFrom failure (attempt #1) - No such host is known ". This was related to my File Location configuration.
In File Locations, URL should be "ftp://ftp1.exacttarget.com" instead of "ftp1.exacttarget.com" which was configured by me. I was transferring a file from a child BU to Parent BU and once I updated the File Location URL, it worked fine.
For other stacks, FTP url are mentioned below.
ftp://ftp1.exacttarget.com if your account uses the S1 instance
ftp://ftp.s4.exacttarget.com if your account uses the S4 instance
ftp://ftp.s6.exacttarget.com if your account uses the S6 instance
ftp://ftp.s7.exacttarget.com if your account uses the S7 instance
ftp://ftp.s10.exacttarget.com if your account uses the S10 instance
