Accessing Plesk Server via Domain Specific FTP Users


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

Thanks for using Lightsail! I recommend taking a quick look at our documentation regarding how to configure Plesk:

For additional configuration help, you can take a look on Plesk site:

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.
