"Unauthorized" error for SFTP connector


I am utilizing the Save Gmail attachments to an SFTP server Flow template to trasnfer reports to an SFTP folder. I have two separate flows I am using to identify emails from two different data sources. They are both configured the same way and have the same gmail and SFTP connections. One of the flows has been working perfectly. The other one worked once or twice and then keeps giving me an "Unauthorized" error. How can I fix this?

Re: "Unauthorized" error for SFTP connector

Hi @ JG2018,


Could you please share a screenshot of the configuration of your flow?


Could you please share more details about the error that you mentioned?

Does the error code of 401 or 403 appears?


In many cases, flows fail because of an authentication error. If you have this type of error, the error message contains Unauthorized or an error code of 401 or 403 appears. You can usually fix an authentication error by updating the connection: 

  1. At the top of the web portal, click or tap the gear icon to open the Settings menu, and then click or tap Connections.
  2. Scroll to the connection for which you saw the Unauthorized error message.
  3. Next to the connection, click or tap the Verify password link in the message about the connection not being authenticated.
  4. Verify your credentials by following the instructions that appear, return to your flow-run failure, and then click or tap Resubmit.

    The flow should now run as expected.

Please let me know if your issue could be solved

Hi Alice, 

Thanks for your reply. I am not getting any 401 or 403 error code. All it says is "Unauthorized" as in the screenshot below.

I have a different flow that is nearly identical to this one except for the Gmail "To" and "From" fields and it is working just fine. Here is the configuration of the flow:
