It’s a usual case that customers need to host multiple domains on the same IP address. So, the FTP server can’t determine the exact account for which the user give the FTP credentials.Īs a result it throws the FTP error 530 valid hostname is expected. In other words, multiple websites have same the set of IP address, Port number, etc. This error commonly happens when users configure multiple FTP sites on the same IP address. That is, it should be the server’s public IP address or server’s internal IP address depending on how the server is configured. In addition to that, we confirm the IP address specified in the binding configuration is a non loop back address. If the FTP host is not configured in the bindings, we’ll add the correct binding for that hostname in the IIS settings. Further, we check the Binding settings of the domain on the server. How we fix?įirstly, our Hosting Engineers get the FTP login details from the customer. As a result, the hostname can’t be resolved externally and the connection can be dropped. Similarly, another common mistake we see is that customers set up the FTP site to bind to the localhost loopback IP address( 127.0.0.1). As a result, the FTP server was unable to identify the FTP host that connects to the server and throws the FTP error 530 valid hostname is expected. We’ve seen many instances where users try to connect to the FTP site using a hostname that’s not configured in the IIS bindings. So, wrong binding settings for the website can always break the FTP connection to the server.
The FTP server uses these details to listen to the requests made to that FTP host.
