      Phillip HallAug 27, 2025
      If your Canon Digital Camera cannot connect to the FTP server, consider these solutions: * Disable the proxy server setting on the camera if you are not using a proxy server. * Ensure the camera's proxy server address and port number match those of the proxy server. * Verify that the proxy server's [Address] is correctly set on the DNS server. * Make sure the IP address on the camera matches the actual FTP server address. * If using encryption, check that the encryption keys match, paying attention to upper- and lower-case letters. * Ensure the port number (typically 21 for FTP/FTPS or 22 for SFTP) is the same on both the camera and the FTP server. * Verify the FTP server's [Server name] is correctly set on the DNS server.
