Disconnected: No supported authentication methods available

Hi, I'm getting this error when connecting to XP machine. Would really like to accept the key and continue working. The full text of error is...
Disconnected: No supported authentication methods available (server sent: publickey, keyboard-interactive)
If I have to manually accept the key that would be OK but would really like to accept automatically.
Here's me code
With mySessionOptions
.AddRawSettings("AuthKI", "1")
.Timeout = New TimeSpan(0, 2, 0) '2 minutes
.Protocol = Protocol.Sftp
.HostName = sIP
.PortNumber = Val(sPort)
.UserName = sUser
.Password = sPassword
.GiveUpSecurityAndAcceptAnySshHostKey = True
End With
Using mysession As Session = New Session
mysession.Open(mySessionOptions)

It's failing on the open command. I've been playing with the .addrawsetting option (tried using hostkey instead of AuthKI with same result) . I've been able to connect to win7 machines with this code. Unfortunatly I still need to connect with XP machines for a time. This is on a company network and I'm really only concerned with what is being sent across the wire so I use .GiveUpSecurityAndAcceptAnySshHostKey = True.
Does anyone know how to accept the key automagically? using vb.net
Regards
Rob

Edit: Attached log

How does the authentication look in GUI? Can you see the "password" when typing it or do you see dots?

Please attach a full log file from a successful (if possible) authentication in GUI (using the latest version of WinSCP).

Thank you prikryl I have attached a log that worked (replaced sensitive info).
FYI: The program grabs user info from a db so there is no typing. This application could potentially hit thousands of servers which is the biggest reason I don't want to use key authentication.

I tried connecting through gui to both the good and bad servers. Attached zip contains both logs.
S=success F=fail
Thanks

Hi Martin,
I'm still trying to work through this issue.
It seems the problem lies somwhere with my code.
I was able to connect through the GUI but am still getting the same message in my program.
I went into the ftpsite and made sure the user i connect with and my IP we specifically given access. This is the same server that was failing yesterday with the GUI. I've attached both logs in hopes you can point me twoard a solution.

I was asking about authentication in GUI.

It shows dots in the GUI.

As I've been working through this, the error message has changed.
It now say's 'Connection has been unexpectedly closed. Server sent command exit status 0.
It's saying that it failed the password check but I am able to log in with the same credentials,
In the program it never gets passed the open statement. The last lines of the log are...

After the change, can you login with GUI? The change may indicate that your account was locked out.

Hi Martin, I finally got this resolved so I thought I would give you aan update.
All the machines that I am connecting to use remotelyanywhere to manage sftp. I saw a few different versions that didn't work but upgrading to v 11 has them all working!
Here's the code I'm using...
With mySessionOptions
.AddRawSettings("AuthKI", "0")
.Timeout = New TimeSpan(0, 1, 30)
.Protocol = Protocol.Sftp
.HostName = sIP
.PortNumber = Val(sPort)
.UserName = sUser
.Password = sPassword
.GiveUpSecurityAndAcceptAnySshHostKey = True
End With

Regards

Thanks for sharing your solution.

Also make sure you understand that you are loosing any security by setting GiveUpSecurityAndAcceptAnySshHostKey = True.
