You should look into your code where you create the authorization URI. You need pass one of the redirect URIs you registered with Google developer console. I guess you're using some OAuth2 library which uses the localhost:port/authorize as the default redirect URI. The port changes because each time you start your local server, it picks a different port number. To fix it, you should specify a port number when starting it, for example, 8080. Then you should register localhost:8080/AddContent.aspx in Google developer console and pass it to whichever library you use to create the authorization URI.
