Does this error occur during
ChangeDirectory method call?
/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);
// 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.
