Make sure you have launched Visual Studio as "Run as Administrator".
The token setup process is organized as a wizard consisting of three steps:
Step 1: Specify the REST service parameters required to initiate the authorization. If there are no parameters, check the next step.
Step 2: Authorize COZYROC SSIS+ to connect to the REST service.
Step 3: If the token retrieval succeeds, the next wizard step will have the access token, refresh token, etc automatically populated in the next step.
Leave the default token refresh date. By default the date shown will allow the token to refresh as needed.
If the automatic token retrieval fails, you can manually specify the access token. If all required information is populated, you can specify the token file name and password to save it.
Tips for successful token retrieve:
Disable the Windows Firewall.
Explicitly start Visual Studio using "Run As: Admin"
Check the box on new token window of Wizard to "Tweak the user Agent..."
Try running the token retrieval from a different machine and move it to your machine.
Log out of the service your are trying to create a token for directly from your machines browsers.
