    I'm using an ispconfig multiserver with a proxy server at front and some servers at the back in a private network
    When I create an ftp user on the proxy server(master server), the user can connect to it, but when I change the server to a backend server(proxied server) or create a new ftp user on it, the server responds "530 Login authentication failed"

    This is the output of the FileZilla logs:

    Status: Connecting to MyIP...
    Status: Connection established, waiting for welcome message...
    Status: Initializing TLS...
    Status: TLS connection established.
    Command: USER user1
    Response: 331 User user1 OK. Password required
    Command: PASS ********
    Response: 530 Login authentication failed
    Error: Critical error: Could not connect to server

    Can anybody help me?

    It's hard to tell you what's causing this. Are you sure traffic is going to the correct server?
