SFTP Functions

Hi team!

Using 'Get Remote Directory Contents Over SFTP' smart service we´re seeing the following error:

2023-01-24 10:06:45,716 [ajp-nio-0.0.0.0-8009-exec-2111] ERROR com.appiancorp.process.engine.UnattendedJavaActivityRequest - An error occurred while executing activity: id=7559, classname=com.appian.ps.plugins.sftpsmartservices.GetRemoteDirectoryContentsOverSFTP

Could you help us to identify the error?

This communication has been in working until last week, so we know that its not a problem with hostname/username/pw.

Thanks in advance.

Hello andrese378,

Have you upgraded the plugin in recent days? Check for the connection in WinSCP tool with the same credentials provided to smart service.

Thanks

Also we have tested the conection to the new customer ftp version in Filezilla and it works, the problem is in Appian.

Hi afiyahamziyas,

Yes, we have the latest version of the plugin.

We have tested it with an old customer ftp version and it works, but with the new customer ftp version it doesnt.

The main difference between that versions is that with the new ftp version, only the comunications with TLS 1.2 or higher are supported, so, supports the plugin TLS 1.2 or higher?

Thanks in advance.
