Hi Junedi,
Did this work earlier anytime, that you are saying it stopped working?
Check all the configurations related to file polling port like directory paths, file name pattern, polling interval, and associated service is properly integrated. I believe you would have done all this correctly but still worth re-checking.
Also sometimes the directory from where the file is getting polled is having relevant permissions and no file is opened on windows or any editor by any chance which is blocking this.
Also once you place the file check the IS logs for any information related to any error causing this issue.
