SFTP Connection creation fails



Trying to create an SFTP connection in flow.


I can connect to the SFTP site using FileZilla without issues.


I add the 'Host Server Address' as DNS name, type in the User Name/PW, add the port number, and check the 'Disable SSH Host Key Validation'


I get the message


Please check your account info and/or permissions and try again. Details: The user does not have sufficient permissions to perform the operation.




Details: Unable to connect to the remote server


Not sure what I am missing.

Hi TerryMc,


From the error message, it seems that your account doesn’t have sufficient permission to perform the action.

Could you please confirm with your administrator about the account information, and try again with the connection?

If you are still getting this issue, please feel free reply.


Best regards,

Thanks for the reply, but still confused, especially when I am the administrator.


Account I am using to create the Flow is an admin account.  I can use them to connect to a gateway to an on prem fileshare, and could copy files to a Sharepoint Online site without issue.


Credentials I use for the SFTP (different from O365) are provided by an external source, but work fine using an ftp client.


What I am trying to do is create a flow to copy files from an on-prem file share to an SFTP site.

Hello @Anonymous, @Anonymous, @Edzka@jefe_, @Anonymous,


Guys i also have faced these type of error, Thuugh i am not so much Aware of the SSL and Certification of Security for HTTP and HTTPS, However then i have Tried the FTP Connector and it's running Flowlessly.


I hope this Idea of Using the FTP connector rather than the SFTP you'll going to by pass the SSL and all other thing and can achive the Goals.

Any fix on the SFTP issue so far?

I'm also having this problem with a SFTP connection to an Amazon Web Services EC2 instance - work perfectly in WinSCP, but not with the Flow SFTP connector.


I've tried everything mentioned here: to make sure my SSH private key and host key finger print are properly specified, but no luck.


The error from Flow is : "Please check your account info and/or permissions and try again. Details: Unable to connect to the remote server"

Using FTP is not a solution if the server you're connecting to only supports SFTP.


The solution is for the Flow SFTP connector to work...

I am still having the same problem. Also how can using FTP instead of SFTP be the solution...

Frequent Visitor

Since no one from Microsoft seems to be addressing this issue, I finally had to break down and configure my AWS EC2 instance to enable password login instead of using the more secure key pair login (, which does work.


Hopefully, someone will eventually respond to this issue, and I can switch back...

I am able to connect using Filezilla, but when trying to configure SFTP in Flow I am getting "invalid SSH Private Key provided".  I too followed the instructions in this very helpful blog post:, but I still cannot make SFTP work in Flow.


Is SFTP working for ANYONE? seems to me we all have the same problem and the only solution is to not use SFTP.  That's not an option for me.


Thanks in advance.

Is this Problem resolved ? In my case I am able to connect to SFTP for some time and as I work on the Flow the connection fails , but when I go to myConnections the SFTP connection status says it's active. Seem Microsoft is not worried about this issue.

I am having a similar problem. 


Is there any known solution for that problem?

I  will strongly appreciate help


Kind Regards





We have the same issue.   It isn't even showing trying to connect on the sFTP side of things.  If we remove the Private Key we get the failure log on the sftp server but the minute we put it back in, it fails and no logging of an attempe on the sFTP server.


Anyway find the solutions?

If your SFTP server does not require a SSH Key then you need to check the Disable SSH Key Validation box.

remove "sftp://" from your address.
