Simple form submission gives missing resource on postback - asp.net-mvc

Question

Apologies if this seems mundane, but I am a huge beginner to MVC and this seemingly simple task is giving me a massive headache.
I can't understand why my code isn't working. I'm submitting a form from my Index.cshtml and the postback is telling me the resource /Index (the page I am posting from) doesn't exist.
Could I please get some help on what I am doing wrong?
My View (Index.cshtml):
#model MyProject.Connection
#{
ViewBag.Title = "Index";
}
<div id="container" class="container centered primary">
#using (Html.BeginForm(FormMethod.Post))
{
<img src="#Url.Content("/Content/images/default.png")" alt="CMGR Web" />
<div class="divider"></div>
<fieldset id="fs_server" class="borderless!T">
<legend>Server details</legend>
<table>
<tr>
<td>
#Html.LabelFor(c => c.serverHost)
</td>
<td>
#Html.TextBoxFor(c => c.serverHost)
</td>
</tr>
<tr>
<td>
#Html.LabelFor(c => c.instanceName)
</td>
<td>
#Html.TextBoxFor(c => c.instanceName)
</td>
</tr>
</table>
</fieldset>
<fieldset id="fs_user" class="borderless!T">
<legend>Your credentials</legend>
<table>
<tr>
<td>
#Html.LabelFor(c => c.username)
</td>
<td>
#Html.TextBoxFor(c => c.username)
</td>
</tr>
<tr>
<td>
#Html.LabelFor(c => c.password)
</td>
<td>
#Html.PasswordFor(c => c.password)
</td>
</tr>
</table>
</fieldset>
<div class="divider"></div>
<table>
<tr>
<td>
#Html.CheckBoxFor(c => c.remember)
#Html.Label("Remember me?")
</td>
<td>
<input type="submit"/>
</td>
</tr>
</table>
}
</div>
My Model (Connection.cs):
namespace MyProject.Models
{
public class Connection
{
[Display(Name="Server Host")]
public string serverHost { get; set; }
[Display(Name="Instance Name")]
public string instanceName { get; set; }
[Display(Name = "Username")]
public string username { get; set; }
[Display(Name = "Password")]
public string password { get; set; }
[Display(Name = "Remoting Password")]
public string remotingPassword { get; set; }
[Display(Name = "Persistent")]
public bool remember { get; set; }
}
}
My Controller (IndexController.cs)
namespace MyProject.Controllers
{
public class IndexController : Controller
{
//
// GET: /Login/
[HttpGet]
public ActionResult Index()
{
return View();
}
[HttpPost]
private ActionResult Index(Connection channel)
{
return View();
}
}
}

Answer 1

Your Post ActionResult is set to Private so it isnt accessible. Change it to public
private ActionResult Index(Connection channel)
{
return View();
}
public ActionResult Index(Connection channel)
{
return View();
}
