Intermittent SFTP server connection issue within Azure logic app consumption

Question

Hi,
I have a Consumption logic app, in this logic app I have a scenario to read data from oracle table and create a file at destination SFTP server. This logic app runs every half an hour to pick up the latest data from oracle table and create a file at SFTP server.

This logic app fails randomly while creating file at SFTP server, error message mentioned below.

Below points are already verified:

• Logic app IPs are already whitelisted at the SFTP server side.
• I am using latest available SFTP-SSH connector for consumption logic app.
• User id and password is correct and user id has all required permissions.
• Data is not huge, only a single line within the file.

Please help me in understanding the root cause of the issue or why this problem generally occurs.
