ASP.NET site authorization issue with google and youtube api's - asp.net

Question

I have implemented several google APIs in my website - to enbale contacts import and youtube uploads.
while everything works great locally (under my own development server's localhost), there are some problems using them thru the site (hosted on both HostGator and 1and1 and i get the same errors everywhere) - seems like
authentication problems.
the site is on ASP.NET 2.0 and these are the error msgs i get:
Error For google contacts (using AuthSub) - this happens after the I successfully receive a session token from google's authsub:
The remote server returned an error: (401) Unauthorized.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Anyone knows what could it be?
Thanks,

Answer 1

I managed to slove it eventually:
as for the first error (authsub and google contacts) - I changed the URI from "http" to "https":
// V1
GAuthSubRequestFactory authFactory = new GAuthSubRequestFactory("cp",gn.ytApplicationName);
authFactory.Token = (String)Session["token"];
ContactsService service = new ContactsService(authFactory.ApplicationName);
service.RequestFactory = authFactory;
ContactsQuery query = new ContactsQuery(ContactsQuery.CreateContactsUri("default"));
// VERY IMPORTANT! adding HTTPS resolves google's bug (401 error)
query.Uri = new Uri("https://www.google.com/m8/feeds/contacts/default/full");
ContactsFeed feed = service.Query(query);
about the 2nd error (ClientLogin) - appearantly google have tightened the security measures around this kind of method - they send a warning email to the user that I wanted to log in through - and only if he follows several complex steps they authorize access to his videos.
As I found out this is not an error, but a policy, I think I'll just switch to AuthSub there too.
Hope I could help someone else too...
