Hi Team,
We received an error while receiving file over SFTP, It is mentioned as Auth fail, though we are using correct credentials for connecting the SFTP, The files were not moving inside, Later we resumed the process instance, it worked. the process will run via MNI node. Can you please help with this issue?
HI, baghavathit0001,
We will try to reproduce the issue and update asap.Can you help us with the log files on the occurrence of this issue
Hi baghavathit0001 ,
We believe it to be a configuration issue from sftp server/appian server. Please try out the below steps
1. Check Hostname, Password username private key and the passphrase configured in the third party credentials is correct in the process model
2. Check if the same file is received using sftp tools like WinSCP.If it works please share the additional configurations if any made in WinSCP to achieve the connection
3. If still unresolvable share us the sandbox environment to replicate the issue
Hi, raghulvishnud,
