Accessing Plesk Server via Domain Specific FTP Users

Question

Hello I created a Plesk server, and while it seems I can create FTP users in Plesk I cannot login with these users. It appears the Plesk Server is configured to only login with a Key.  I have the master key for my main FTP account, but when I use it for the domain specific FTP account it gives me an error. Is there a way to generate a new key specific for these FTP users that are created in Plesk?  
  
Here is the error:  
  
Error: FATAL ERROR: No supported authentication methods available (server sent: publickey)  
Error: Could not connect to server  
  
I attempted to login with the default key and I get the same error. Is there a way to get a key for these additional users?  
  
When I opened port 21 for FTP traffic and attempt to login with FTP over TLS, I receive this error:  
  
Status: Retrieving directory listing...  
Command: PWD  
Response: 257 "/" is the current directory  
Command: TYPE I  
Response: 200 Type set to I  
Command: PASV  
Response: 227 Entering Passive Mode (***********).  
Command: MLSD  
Error: The data connection could not be established: ETIMEDOUT - Connection attempt timed out  
Error: Connection timed out after 20 seconds of inactivity  
Error: Failed to retrieve directory listing

Hi,  
  
Thanks for using Lightsail!  I recommend taking a quick look at our documentation regarding how to configure Plesk:   
https://lightsail.aws.amazon.com/ls/docs/en_us/articles/set-up-and-configure-plesk-stack-on-lightsail.  
  
For additional configuration help, you can take a look on Plesk site:   
https://docs.plesk.com/en-US/onyx/deployment-guide/plesk-installation-and-upgrade-on-public-cloud-services/installing-plesk-on-amazon-lightsail.79028/   
and   
https://docs.plesk.com/en-US/onyx/deployment-guide/plesk-installation-and-upgrade-on-single-server/plesk-single-server-postinstall-configuration.76454/  
  
If you are still running into trouble, we can definitely help take a look.

Hi Davidly,  
  
Thank you for the response! But I don't think this issue is covered in any of the resources.   
  
I'm surprised I cannot find anything on this because it seems pretty straightforward. Lightsail appears to configure the plesk server to login with the ubuntu user with the SSH key. However, when I create an FTP user in Plesk for a specific domain, i can't find anyway to login with that user. The password I create doesn't work as it appears from the error that it is asking for the key. But the main SSH Key Lightsail provides doesn't work.  
  
I could change the permissions for the ubuntu user to own the folder paths to these domains, but for what I am doing i would much rather use the FTP user that is created by plesk when i add the domain.   I feel like I'm the first one to try to do this, none of the tuturorials i've found on Udemy or Youtube go over how to do this.
