Can't access login on Thinktecture IdentityServer3 from JavaScript client

I built IdentityServer pretty much following the tutorial with mvc client. http://identityserver.github.io/Documentation/docs/overview/simplestOAuth.html IdentityServer works fine with the mvc client, but I'm using a javascript client, so I downloaded the javascript sample: Javscript Implicit Client: https://github.com /IdentityServer/IdentityServer3.Samples/tree/master/source/Clients/JavaScriptImplicitClient

When I try to login from a client, it always comes back with "Client application unknown or not authorized."

Can anyone point me in the right direction? Is there a way to enable logging to find out why the client is being rejected?

Relevant javascript code:

 var config = {
        authority: "https://localhost:44302/identity",
        client_id: "mws",
        redirect_uri: window.location.protocol + "//" + window.location.host + "/index.html",
        post_logout_redirect_uri: window.location.protocol + "//" + window.location.host + "/index.html",

        // these two will be done dynamically from the buttons clicked
        //response_type: "id_token token",
        //scope: "openid profile email read write",

        // we're not using these in this sample
        silent_redirect_uri: window.location.protocol + "//" + window.location.host + "/silent_renew.html",
        //silent_renew: true,

        // this will allow all the OIDC protocol claims to vbe visible in the window. normally a client app 
        // wouldn't care about them or want them taking up space
        filter_protocol_claims: false
    };

      

        
        
        
      

    

Server side client definition:

new Client
            {
                Enabled = true,
                ClientName = "Manager Workstation",
                ClientId = "mws",
                Flow = Flows.Hybrid,
                RequireConsent = true,
                RedirectUris = new List<string>
                {
                    "https://localhost:44303/index.html"
                },      
                PostLogoutRedirectUris = new List<string>
                {
                    "https://localhost:44303/index.html"
                }
            }, ...
