Overview

This article describes the issue when the FTP User Experience Monitor Produces the following error:

The underlying connection was closed: The server committed a protocol violation.

Product section

Server Application Monitor

Cause

One cause of this error occurs when trying to use the FTP User Experience Monitor to check SFTP or FTPS.

Resolution

SAM currently doesn't support SFTP or FTPS with the FTP User Experience Monitor.

To get this functionality we recommend looking into custom scripts to achieve this.

If you are using the FTP User Experience Monitor for FTP only and still receiving the above Error.

Please edit the Application Monitor and change the FTP monitor to Passive Mode as this has resolved some "False protocol Errors" in recent cases.

Active mode - Client open one channel to server and then server opens data chanell back from server to client.
Passive mode - Both channels are opened from client side

Please note that Solarwinds Technical Support cannot assist with the customization of scripts. For assistance in this regard we recommend asking in the Thwack Script Lab forum.
