I'm suddenly starting to get the following exception when attempting to authenticate and access a spreadsheet on Google drive:
Unhandled Exception: Google.GData.Client.GDataRequestException: Execution of aut hentication request returned unexpected result: 404 at Google.GData.Client.Utilities.getAuthException(TokenCollection tokens, Htt pWebResponse response) at Google.GData.Client.Utilities.QueryClientLoginToken(GDataCredentials gc, S tring serviceName, String applicationName, Boolean fUseKeepAlive, IWebProxy prox yServer, Uri clientLoginHandler) at Google.GData.Client.GDataGAuthRequest.QueryAuthToken(GDataCredentials gc) at Google.GData.Client.GDataGAuthRequest.EnsureCredentials() at Google.GData.Client.GDataRequest.EnsureWebRequest() at Google.GData.Client.GDataGAuthRequest.EnsureWebRequest() at Google.GData.Client.GDataRequest.Execute() at Google.GData.Client.GDataGAuthRequest.Execute(Int32 retryCounter) at Google.GData.Client.GDataGAuthRequest.Execute() at Google.GData.Client.Service.Query(Uri queryUri, DateTime ifModifiedSince, String etag, Int64& contentLength) at Google.GData.Client.Service.Query(FeedQuery feedQuery) at Google.GData.Documents.DocumentsService.Query(DocumentsListQuery feedQuery ) at GoogleLogger.GoogleService.getLastXECLogRows(String folderName, String fileName, Int32 rows)
This is in code that has been running for two years without any problems. I first thought that I may have lost access permissions on my production system but Google drive loads fine in my web browser. Tried it on several other systems and am getting the very same.
Did they change something in the Google API today? This can't be coincidence!
