WebWare Interlink Error -400 [WebWare Server]


      We have been running webware 4.6 for a bit over a year now with very few issues. The system was regularly backing up 12 S4C+ robots. It seems as though after a certain date (I dont know the significance) all robot backups started "Completing with Errors". No actual backup files are present now and the error code is -400 (FTP General Error)   

Any help would be greatly appreciated!
