Need Need to configure FTP site on Server 2012 for SFTP
We have a cloud application that up until 6 weeks ago, was able to send SFTP file transfers to our FTP server. Now only FTP connections can get through. I am not an expert at FTP but we set it up years ago and the SFTP connection worked fine. Now that it fails, I don't know where to look or where to enable the SFTP connection. Any suggestions on where to look would be appreciated.

Does it work internally? If yes then the problem is with the firewall configuration blocking the connection. If not, it can be a number of things. Whichever FTP client you are using there should be some kind of logging feature. You should see why it failed to connect and the error message. Please post the error.

I posted the logs from the client and the server. Not sure why the server log is recording the wrong time. Both client and server show the same date and region.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Windows FTP only has FTPS not S/FTP (secure shell ftp) so you need a 3rd party ftp server like filezilla (recommended even for just ftp)
What SFTP server are you using? As others pointed out, Windows Server does not come with an SFTP server (only FTP).
ASKER
Thanks for the information on Filezilla
You might also consider using a commercial solution so you will have access to Technical Support. Robo-FTP Server (https://www.robo-ftp.com/robo-ftp-server), for example, runs on Windows, supports SFTP, can be set up in minutes, and offers advanced features like a skinnable web interface for securely uploading files via a web browser, including the option to enable end-to-end encryption (performing automatic PGP encryption on the user's system before uploading).
