We are a cloud customer attempting to connect from Appian to an internal sFTP server over the VPN tunnel to retrieve a file for processing. We are receiving the following error message within Appian when we attempt to connect:
Error message: 16:22:40,745 INFO [stdout] (Appian Work Item - 41212 - ProcessExec01 : UnattendedJavaActivityRequest) com.appiancorp.suiteapi.process.exceptions.SmartServiceException: userMsg[error.sftp_conn=Error establishing SFTP connection. Confirm your hostname, username and password. See application server log for more details. Error Message: Algorithm negotiation fail]
Has anyone experienced this issue?
