@Oblivion, thanks for your prompt answer!

I try test the demo SFTP server which you provided, it seems work well.

However, when I switch to my SFTP server, it have the same error which I describe in last post.
I am sure my SFTP user name & password is correct and have write access right.

I guess may be dir/path error, you also mention it, so I adjust connect() function to manual set basedir as below.

session.Timeout(settings.timeout * 1000);
	if((connected = session.Connect(
		~settings.host,
		~settings.port,
		~settings.user,
		~settings.password
		))) {
		browser.Attach(new SFtp(session));
		filesystem.Mount(*browser);
		basedir = browser->GetDefaultDir();
		basedir = "msp";//add for testing
		DLOG(basedir);
		dir.SetData("msp");//add for testing
		DLOG(dir.GetData().ToString());
		DLOG(GetWorkdir());
		DLOG("Before work dir");
		Workdir(basedir);
		DLOG("After work dir, and before LoadDir");
		LoadDir();
		DLOG("After load dir");
	}
	else SessionError();
}

The list still empty, but I am able upload file or create sub folder without error. And other SFTP software does show the file & folder created too.

So, that means, loaddir() function have issue.
Not able successful list folder & files.
After add more DLOG, I am sure it caused by below:
if(Upp::Load(list, GetWorkdir(), "*", false, Null, (FileSystemInfo&) sfsi, Null, false))
sortbyext ? SortByExt(list) : SortByName(list);

LOG:

I try add more DLOG:

void SFtpBrowser::LoadDir()
{
	if(browser->InProgress())
		return;
	list.Clear();
	DLOG("Before SFtpFileSystemInfo sfsi(*browser);");
	SFtpFileSystemInfo sfsi(*browser);
	DLOG("After SFtpFileSystemInfo sfsi(*browser);");
	DLOG("Before If");
	DLOG(GetWorkdir());
	if(Upp::Load(list, GetWorkdir(), "*", false, Null, (FileSystemInfo&) sfsi, Null, false)){
		DLOG("Before sort");
		sortbyext ? SortByExt(list) : SortByName(list);
		DLOG("After sort");
		}
	DLOG("After If");
	DLOG("Before Summary()");
	Summary();
	DLOG("After Summary(), and before Sync()");
	Sync();
	DLOG("After Sync()");
}

Any way to fix it?
