    Hi,

    The FTP is working fine since we setup the Plesk Linux 9.5 but it's not working suddenly. It shows the below message when we tried to connect:

    Status: Connection established, waiting for welcome message...
    Error: Connection timed out
    Error: Could not connect to server

    We've checked the firewall setting, there's nothing wrong with it, we don't made any changes on it as well. We've restarted the Apache but still not working.

    Any idea or suggestions?

    Thanks.

    Did you tried to check that port 21 is open with

    lsof -i tcp:21

    for example?
    Did you tried connect to FTP server with telnet, for example?

    Yes, our support has fixed it by changing the Plesk Linux server Network DNS to another IP, then it's worked. It's kind of weird as it's working fine all these whiles, just out of sudden, all servers are not working as it can't resolve the DNS IP address. Any idea what it caused to the DNS functional problem?

    Thanks.
