SSH ciphers on SCP

I recently installed Solarwinds free-sftp-server and it works fine. But I found I have issues uploading some switch configurations (Protocol error).

In logs found only this message that looks suspicious:

Feb  7 14:31:17.850: SSH2 0: no matching cipher found: client aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc server aes128-ctr,aes192-ctr,aes256-ctr,chac

According to switch guy, switches are old and its problem to add cbc ciphers on his end.Is it possible to configure what ciphers is allowed on my SCP server, couldnt find any settings for that?
