I could access SFTP from WinSCP using the below credentials
Lib used:
I get the below error when try to connect programmatically using Java. When I browsed google for the error, all I could get was special character ! is used in password. Therefore use UriParser.encode(sftpuri) that will resolve the problem but unfortunately it didn't help.

Below is the code I'm using for downloading file from SFTP.
Blog reference: https://www.mysamplecode.com/2013/06/sftp-apache-commons-file-download.html
Output for UriParser.encode(sftpUri). I could infer that the PORT is not appended here
sftp://orafusion:[email protected]/TestData/TestFile.txt
I get error at the below line of code
FileObject remoteFile = manager.resolveFile(UriParser.encode(sftpUri), opts);
props = new Properties();
StandardFileSystemManager manager = new StandardFileSystemManager();
props.load(new FileInputStream("D:\\common.properties")); // + propertiesFilename));
String serverAddress = props.getProperty("serverAddress").trim();
String userId = props.getProperty("userId").trim();
String password = props.getProperty("password").trim();
String remoteDirectory = props.getProperty("remoteDirectory").trim();
String localDirectory = props.getProperty("localDirectory").trim();
//Initializes the file manager
manager.init();
//Setup our SFTP configuration
FileSystemOptions opts = new FileSystemOptions();
SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(opts, "no");
SftpFileSystemConfigBuilder.getInstance().setUserDirIsRoot(opts, true);
SftpFileSystemConfigBuilder.getInstance().setTimeout(opts, 10000);
//Create the SFTP URI using the host name, userid, password, remote path and file name
String sftpUri = "sftp://" + userId + ":" + password + "@" + serverAddress + "/" +
remoteDirectory + fileToDownload;
// Create local file object
String filepath = localDirectory + fileToDownload;
File file = new File(filepath);
FileObject localFile = manager.resolveFile(file.getAbsolutePath());
System.out.println("sftp uri : " + UriParser.encode(sftpUri));
// Create remote file object
FileObject remoteFile = manager.resolveFile(UriParser.encode(sftpUri), opts);
// Copy local file to sftp serverF
localFile.copyFrom(remoteFile, Selectors.SELECT_SELF);
System.out.println("File download successful");
You are using FTP in WinSCP, not SFTP. These are two completely incompatible protocols.
Or possibly the encrypted variant of FTP, the FTPS (FTP over TLS/SSL) – what might lead you to the confusion with SFTP.
Replace the sftp:// in your URL with ftp:// or ftps://.
