Hello team!

I get this error when I try to connect to sftp server. Reflector 1.00 was installed as a application (nos as service).

For your information, I can connect to the server through winscp for example.

Any idea? Thanks!! ;)

What kind of server are you using? Filezilla?

Hello! I have the same error during connection to SFTP server:

Failed to connect - closing connection
The negotiation of host key verification algorithm has failed


Some people say I have to edit "known hosts" file and remove the old key for the host I'm trying to connect to. Could you please tell me, where this file is located?

The file should be located att %USERPROFILE%\.ssh (often c:\Users\<your user name>\.ssh (.ssh is a hidden folder)
