SFTP error message: Authentication type [16] failed

Post by naeco »

Hello!

I'm setting up a new SFTP connection to a client's server and getting the error message (in bold red):
(15:53:58) [1] Connecting to ***SFTP
(15:53:58) [1] Resolving sftp.*****.com...
(15:53:59) [1] sftp.****.com => ###.###.###.###
(15:53:59) [1] Connecting to ###.###.###.###:22

After exchanging the issue with the tech support of my client, he suggested that error message could be due to the lacking of a public key for authentication.

So by using PuttyGen, I created one with RSA protocol. However, the key I provide to them didn't work with their server (although he specifically indicated that their server would only work with RSA protocol). Creating another key with older version SSH-1 didn't work out either.

As a result, we both tried to ignore the error and set up the connection for a test run (after removing all references to the SSH key). The connection was established but when the file transfer started, it failed (minute 15:54:16 in the quote).

Same settings were used on another FTP client and the file transfer was done without errors. We came to conclusion that some local settings in FTP Rush prevent the SFTP process. I went through all the settings but couldn't identify what could cause the error.

I'd really appreciate if someone could help me troubleshoot this. I've been using FTP Rush for years and prefer not having to switch to another client.

Thank you!

I had similar problems, did you tried to upgrade your ssl binaries?

take a look on : http://slproweb.com/download/Win32OpenSSL-1_0_2g.exe" rel="nofollow

1/ install it in system
2/ install it in local folder (like c:\openssl)
3/ copy libeay32.dll and ssleay32.dll in FTPRush installation folder (shut it down before)
4/ restart FTPRush and see if it's ok (it should)


outdated ssl can be your problem. sometimes error msg are wrong, wrong password, wrong this, wrong that, but infact it's because of outdated ssl.

hope this help.
