Issue
When connecting to an SFTP server to publish data using a Com'X 200/210/510, it gives an error: "Could not parse response code. Server Reply: SSH-2.0"

Product Line
Com'X 200/210 (EBX200/EBX210)
Com'X 510 (EBX510)

Environment
Com'X 200/210/510 Publishing Data to SFTP server

Cause
SFTP is not supported for data publishing in the Com'X 200/210/510 series. The remote SFTP Server is expecting to use SFTP protocol and SSH connection rather than FTP.

Resolution
The 4 supported Transfer Protocols for the Com'X 200/210/510 series are:

1. HTTPS
2. HTTP
3. FTP
4. SMTP

For publication, FTP is not recommended. Instead use either HTTPS with authentication, or SMTP with either SSL/TLS or SMART TLS.

If FTP is the only option, then port 21 on remote server needs to be open.
Connection on Port 21 is for FTP and Port 22 is for SFTP/SSH.
