Hello!

Yes, it worked by putting the IP directly instead of the server name, it does not resolve with the DNS name.

Regards

Hello, Any idea why I would keep getting this error message? What exactly does it mean:-

Cannot invoke "Object.toString()" because the return value of "com.appian.ps.plugins.sftpsmartservices.SFTPConfig.getSftpChannel()" is null

Hello,

We have been having the same issues with our connectivity to a new SFTP service. What we have found is the new SFTP service is using newer cyphers and which Appian SFTP plugin v3.0.3 does not support.
