 Hi! I'm doing some coding with libssh2 v0.12 on windows 7 Pro 64 bits to
 connect to Huawei routers. On some routers works fine, on others just echo
 this error: "Warning: ssh2_connect(): Error startingup SSH connection(-8):
 Unable to exchange encryption keys in (...)". I used putty on same routers
 and the sessions logs are identical:
 2015-05-27 12:02:19 Server version: SSH-2.0-HUAWEI-1.5
 2015-05-27 12:02:19 Using SSH protocol version 2
 2015-05-27 12:02:19 We claim version: SSH-2.0-PuTTY_Release_0.63
 2015-05-27 12:02:19 Doing Diffie-Hellman group exchange
 2015-05-27 12:02:19 Doing Diffie-Hellman key exchange with hash SHA-1
 2015-05-27 12:02:32 Host key fingerprint is:
 2015-05-27 12:02:32 ssh-rsa 512

 2015-05-27 12:02:32 Initialised AES-128 CBC client->server encryption
 2015-05-27 12:02:32 Initialised HMAC-SHA1 client->server MAC algorithm
 2015-05-27 12:02:32 Initialised AES-128 CBC server->client encryption
 2015-05-27 12:02:32 Initialised HMAC-SHA1 server->client MAC algorithm

 Can you help me?
 Thanks!
