This generic error indicates the Janrain's service does not accept your configuration settings.
The RPX login part cannot be used out of the box, as it requires separate configuration for each site that you build.
More details can be found in these topics: http://www.mono-software.com/Mono/Pages/Discussion/dtopic/Hy6RHa6tX06r8p6KATl6gQ/RPX-Getting-it-to-work/ and http://www.mono-software.com/Mono/Pages/Discussion/dtopic/phTU6_Zfc0edKp9kAVwdcg/NA/?pageno=2&dmsgId=dtoCpj3tKkmqVJ9kAYk8Jw#PostdtoCpj3tKkmqVJ9kAYk8Jw
You will also need to open an account at Janrain site and configure the providers you want to use.       

I have an active account and just testing the app on their site and it worked and displayed back the json response. But when I sent the token url it put me to my instance of mono x and I got the same error. Is there something I am missing at Janrain?

Here is what I have on the login.aspx page

<MonoX:LoginRpx runat="server" ID="ctlLoginRpx" Width="100%" ApiKey="I removed this key from this post..." RpxFrameUrl="https://bpaahost.rpxnow.com/openid/embed?token_url=http%3a%2f%2fsupport.bpaahost.com%2flogin.aspx&language_preference=en&flags=show_provider_list" />

forgot to mention I have the domain whitelisted for the token url

If you set up the providers on their end correctly, the only thing that looks wrong is the RPXFrameUrl - it should not hold any parameters (like your token_url).

ok, I'll try removing the parameters. I'll let you know
