I am getting the error "Please check your internet connection and try again". I do have internet connection and have allowed the app through the firewall.

If you are getting an internet connection error, please make sure you have selected TLS 1.2 under your machine internet options. To do that, follow the below steps:

Control Panel > Network & Internet >Internet Options/Properties

Under "Advanced" tab select "TLS 1.2" check box and click ok.
