Hi, I'm having issues accessing a folder on our SFTP server. This was working before and there have been no code changes. I'm currently getting the error 'No Such File; no Such Directory' below is the log text:

Does this error occur during ChangeDirectory method call?

If /IOC/ITF actually exists, that would mean the error is caused by a server-side bug in SSH_FXP_STAT command implementation. In that case, we recommend contacting the server vendor to have it fixed.

Alternatively, you might upgrade to Rebex SFTP 2020 R2 which has an experimental workaround for servers with broken SSH_FXP_STAT command. The following code shows how to enable the workaround:

var client = new Sftp();
client.LogWriter = new ConsoleLogWriter(LogLevel.Debug);
client.Login("demo", "password");

// enable experimental workaround for broken SSH_FXP_STAT
Security.Cryptography.CryptoHelper.SetOption(client.Settings, "EnableDataPowerSshWorkaround", true);


If you give this a try, please let us know whether it solves the issue.

Thanks for the quick response.... issue is resolved..... issue was caused by recent updates to the server causing some of the accounts access to change.
