Hi community,

 

I'm configuring a Data Source, that connect to a server via SFTP method. However, when I try:

 

file retrieval method: SFTP

server : abc.com

username: admin

password: aaaaaaa

filepath: /abc/file.csv

 

It shows this error: java.io.IOException: SSH authentication failed, DNS cannot resolve host abc.com:22 to an IP address while opening a connection. Error in Screenshot below

Does anyone know what this error referring to and how to fix this?

 

Regards,

Rahul
