Resolved Impossible to make a FTP connection

[Django]

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

Plesk Obsidian Web Host Edition Version 18.0.49 Mise à jour n° 2

Hello . I'm not an expert of servers management or Plesk (although I already made about 100 professional websites on Joomla/CPanel), but on my new VPS/Plesk on IONOS, I can't make a FTP connection working. Main account or other users.
The messages of my FileZilla (domain and username replaced) :

Status: Connecting to mydomain.com...
Response: fzSftp started, protocol_version=11
Command: open "[email protected]" 22
Command: Trust new Hostkey: Once
Status: Using username "username".
Command: Pass: **********
Status: Connected to mydomain.com
Error: Could not connect to server


I have no idea what I have to change.
Protocol SFTP - SSH
For the hostname, is it the domain, the IP, with ftp:// at the beginning .... ?
For the user and password, I think I have them
Any other parameters to check in Plesk ?

Looks like you're trying to connect using SSH, if the user account you're using doesn't have ssh access it won't work, try connecting use normal FTP over port 21 instead.

Thanks. That was it. I just had a connexion working with SSH / root . Now I'm wondering where my sites files should be.
At the moment, they are at : /var/www/vhosts/mysite1/httpdocs
Is it the right folder ?
Or is it at : /var/www/vhosts/site1, or : /var/www/html/site1 ?

 

[scsa20]

Default path for uploading files to is /var/www/vhosts/domain.tld/httpdocs for files, subdomains is usually /var/www/vhosts/domain.tld/subdomain.domain.tld

Thanks a lot. So, it was correct. I discover Plesk little by little...

 

[bonar]

can you share me how to resolve this ?

Hello. Sorry, by I gave up with Plesk, and closed my account. You have to be a web hosting specialist to use it. I fell much more comfortable with CPanel. So, I'm not able to help you.

You have to be a web hosting specialist to use it.

Well than is is surprising how many users are specialists. Plesk is running on more than 384,000 servers, automating more than 11 million websites and more than 15 million mail boxes. Available in more than 32 languages across 140 countries, 50% of the top 100 service providers worldwide are partnering with Plesk today.

You're probably right, and maybe I shouldn't have said that on the Plesk forum, but the fact is that I find Plesk much more difficult to use than CPanel. After more than a hundred professional websites created.

 

[scsa20]

I don't know, I find cPanel's WHM annoying and limited, personally, after having to deal with it for a few years. I find myself going back to Plesk each time because I just prefer the way the panel does things but hey, each their own.

Has anyone solved this issue...?

I have the exact same problem, I've never needed to add an additional ftp user in Plesk before but now I need to provide access for developers, I've spent 2 hours trying to resolve the issue, it should be so simple adding a FTP user but I also get:

Status: Connecting to 123.123.12.123...
Response: fzSftp started, protocol_version=11
Command: open "[email protected]" 22
Status: Using username "dev".
Command: Pass: *********
Status: Connected to 123.123.12.123
Error: Could not connect to server

Only the system user can have access which I dont want to give out to strangers, theres no way to authorise SSH when adding and additional FTP user only provides inputs for user name, directory and password entries

Can anyone help for a solution, I'm using filezilla SFTP

 

[Raul A.]

By default all additional FTP users can connect only via FTP and FTPS (on port 21). They have /bin/false shell which is not a valid shell for SSH or SFTP access (on port 22).

You can grant access using SSH-Keys and the system user. This will grant access to the developer to the entire webspace.

The limitation for additional FTP users is due to how the SSH protocol works. The parent of the SSH user home folder must be root owned.
