Troubleshooting Connection Issues

If you encounter an error message similar to:

"There was an error uploading the file to the SFTP server. Could not establish SFTP connection with host: 'sftp.domain' at port: '##' - Unable to negotiate key exchange for server host key algorithms ..."

this indicates that the SFTP server you are trying to connect to does not support any of the ciphers compatible with the dataloader.io SFTP client.

In such cases, you may need to check the configuration of the SFTP server or contact your server administrator to ensure that it supports the necessary ciphers to establish a successful connection.

For other issues, please, refer to the SFTP connection main article.
