Help setting up a remote host

I followed the instructions (1st using SSH to create the key remotely, and then with PuTTY) and get the following error when probing the remote host:OpenSSH_7.3p1, OpenSSL 1.0.2j 26 Sep 2016 debug1: Reading configuration data /c/Users/Alex/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug1: Connecting to 192.168.0.126 [192.168.0.126] port 22. debug1: fd 3 clearing O_NONBLOCK debug1: Connection established. debug1: key_load_public: No such file or directory debug1: identity file /c/Users/Alex/.ssh/id_rsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/Alex/.ssh/id_rsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/Alex/.ssh/id_dsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/Alex/.ssh/id_dsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/Alex/.ssh/id_ecdsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/Alex/.ssh/id_ecdsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/Alex/.ssh/id_ed25519 type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/Alex/.ssh/id_ed25519-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_7.3 debug1: Remote protocol version 2.0, remote software version OpenSSH_7.4p1 Debian-10+deb9u1 debug1: match: OpenSSH_7.4p1 Debian-10+deb9u1 pat OpenSSH* compat 0x04000000 debug1: Authenticating to 192.168.0.126:22 as 'smartcoin' debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: algorithm: curve25519-sha256@libssh.org debug1: kex: host key algorithm: ecdsa-sha2-nistp256 debug1: kex: server->client cipher: chacha20-poly1305@openssh.com MAC: <implicit> compression: none debug1: kex: client->server cipher: chacha20-poly1305@openssh.com MAC: <implicit> compression: none debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ecdsa-sha2-nistp256 SHA256:mYGSvlz1/eP19p+zmm24Zta05S/2H4wTAdhgNgpvMzg debug1: read_passphrase: can't open /dev/tty: No such device or address Host key verification failed.
