EDI import process will not recognize the current EDI import folder

Hi,
Over the weekend something happened and we cannot get our EDI Import process to recognize the current EDI import folder. The folder lives on a different server other than our Epicor 9 server. We can transfer the import files to a folder on our Epicor 9 server and then the import works. Not sure what could have happened. Any suggestions?

This is the error we get:

Exception caught in: Epicor.Mfg.Proc.ImportEDI
