Issues with Redirect(authUrl);

[techgeeksquared]

I cannot get past this, the return Redirect(authUrl); fails and I get a XML message, "An error has occurred.". I'm connecting to the live server which is HTTPS. I verified the clientID as well as the other variables is the authUrl string. I verified the API Client setup on the live site is active and the call back url is: http://localhost:49676/token. When I change to debug and run nopcommerce with the api plugin locally it works, even if I use the same db as the live site. So I know it can create the authorization code. I'm pretty sure the issue is with getting it to refresh the token but, I can't get it past this point to refresh it. The return doesn't throw a direct exception, it continues on to the outer bracket and then throws the error on the api application's web page.

Any ideas are greatly appreciated.

Did you manage to solve this problem? I'm using exactly the same code and I have exactly the same problem.
