FATAL ERROR: Received unexpected packet when expecting ECDH reply, type 1 (SSH2_MSG_DISCONNECT)
I was able to connect to this server until I removed some insecure ciphers, mac algorithms and kex algorithms form the server. I reverted the changes and still get the error.
I can successfully connect to the SFTP using WinSCP or command line.
Here is the full log.
