AMEX connection was not successful

in Ask A Guru 3 comments

Hello Team,

We are experiencing an issue connecting to AMEX via the FSGATEWAY Live SFTP server. Despite entering valid credentials, the connection is rejected with the following error:

"FTP_CANNOT_ESTABLISH_CONNECTION: Could not establish connection to No more authentication methods available."

The error originates from the com.netsuite.amexcardintegration SuiteApp (psa_amex_sftp.js). Based on the error message, we suspect the server may require SSH key-based authentication rather than username/password alone, but we are not certain.

Has anyone encountered this issue or successfully configured SFTP authentication for the AMEX Card Integration SuiteApp? Any guidance would be appreciated.
