WinSCP is able to login but passes wrong/no password to PuTTY

As the title says it clearly:

• I added a new server (in fact I have 50 servers, all SFTP, everyone login is working as expected – even with PuTTY login)
  
• Set password and told WinSCP to remember it.
  
• The start password was password.
  
• Ctrl+P -> PuTTY starts and the shell is visible (login is working)
  
• Now I set a new password – close the connection, login again with WSCP.
  
• WinSCP shows "Wrong password" – I type in the new one and enabled the "Update my stored password" box (text in German, might not the 1:1 version in English).
  
• WinSCP knows now the new password – login is working.
  
• [m]Ctrl+P: PuTTY starts: "Access denied"[/b]
  

So – whats is wrong here? I did that 1000 times, this is working everytime! Except for this one.

Some facts:

• WinSCP 5.17.7
  
• PuTTY 0.74 x64
  
• The password for that server contains § % " and { as special chars.
  

A log is attached.

Do you mean that you did whole this sequence (with the password change) many times and it was always working? It works for me too. Can you reproduce the problem? Does opening PuTTY work, if you now login directly with the updated password?

Yes – it always worked.

No, it is NOT working with
I have the password in the clipboard. I pasted it for -pw – access denied.

I paste it immediately after "Access denied" -> Is working. So it seems not to be a WinSCP issue. I think my password has a special character in it which is not correctly forwarded by PuTTY.

Remember: I have §%" and { in it. I believe this causes the issue? Maybe the "?

The issue is § AND ". Ive changed pw with one of it in it. None of them worked.

EDIT: CHanged password to one with no special chars in it: Working!

WinSCP does not have this issue while using SFTP.

Thanks for sharing your findings.
