Failed to exchange authorization code for access token.

Hi Team,

I'm trying to build an Ad and Campaign for a Webapp using the Google's AdWorks API.

1. I created the OAuth 2.0 ClientID details using 'https://console.cloud.google.com/apis/'. 

2. I used the client details in the web.config of AdWords.Examples.CSharp.OAuth and tried the 'Authorize User' action on the 'AdWords API OAuth demo' page.

Issue: While trying the 'Authorize User' in step 2 above:

1. Refresh token got generated.

2. Error below occured for the access token: 

[Google.Api.Ads.Common.Lib.AdsOAuthException: 'Failed to exchange authorization code for access token.'].

Please advise on the resolution for above.
