Seems like what ever cipher your server is negotiating is not available on the client. You can set cipher strings on the .connect event in index.js file around line 125-129. master branch has these set to work with some Cisco routers that have trouble negotiating higher cipher strengths. exec-test branch has this commented out.

This is not as much an issue with WebSSH2 as it is providing the proper cipher strings to pass to the ssh2 module by @mscdex

Check out that page for the proper cipher settings. You can also enable debug mode in both your sshd on the server side as well as ssh2 here by adding a debug function to the .connect event in index.js.

    }).connect({
        host: config.ssh.host,
        port: config.ssh.port,
        username: config.user.name,
        password: config.user.password,
        debug: console.log,
        tryKeyboard: true
    });
