We currently have such problem in the Visual Studio extension for AppBuilder, but it does not seem to be true for AppBuilder for Windows client.
If the problem persists, in order to help you further, we would need session logs from FiddlerCap (with the Decrypt HTTPS Traffic option enabled). Start it prior AppBuilder and save the HTTP requests to disk. Zip the sessions and upload them to a free file share site and give us the link here or alternatively open a support ticket and attach it in the ticket.
