Causes and Fixes When WinSCP Cannot Connect to a Server

When using WinSCP for data management and transfer, being unable to connect to a server can cause significant inconvenience and work disruption. Below are some common causes and their fixes:

• Incorrect login credentials: Ensure you have entered the correct IP address or domain name of the server, connection port, username, and password. Pay particular attention to uppercase and lowercase characters, as they can affect login.
• Server is not running: Check whether the server you are trying to connect to is operational. You can try pinging the server's IP address or use other tools to check the server's status.
• Incorrect connection protocol: Ensure you have selected the correct connection protocol (SFTP, SCP, FTP, WebDAV, or S3). If the server does not support the protocol you are using, the connection will fail.
• Firewall or proxy settings: A firewall or proxy may block WinSCP's connection to the server. Ensure that the connection ports (typically port 22 for SFTP or port 21 for FTP) are open on both your computer and the server. If using a proxy, configure it correctly in WinSCP's Preferences.
• Public key authentication failure: If you use public key authentication, make sure your public key is properly installed on the server and your private key is correctly selected in WinSCP. Also ensure the format and access permissions of the key files are correct.
• Server overload or software errors: If the server is overloaded or experiencing errors, the connection may be refused. Try reconnecting after a few minutes or contact the server administrator.

To resolve the issues above, you can re-check the connection details, try changing the protocol or connection port, and review firewall and proxy settings. If the problem persists, check the detailed error messages that WinSCP provides for more specific information about the cause.
