Description:
------------
ssh2_connect function can't establish a connection to the server. It give this error:

"Error starting up SSH connection(-5): Unable to exchange encryption keys"

It worked but maybe after an upgrade I have this problem. I don't know if the upgrade regard server or client. 
Obviously the server is up and ssh connection with ssh command prompt work fine.  

Test script:
---------------
$this->connection = ssh2_connect($host, $port);

You may need a newer libssh2[1], in which case this would not be a PHP issue.

If you still have this issue, please mention the version of PHP,
ssh2 and libssh2 you are using.
