Unable to Update Device Cores/Packages/OS

Scenario:

When trying to do an update or load a new Device Core, Package, or Operating System (update only) an error occurs or the update will not progress. 

Fix:

1. Check there is internet connection available for your Blue Pill device

2. For updates the Blue Pill needs to be able to access pkg.skaarhoj.com on https to do updates via port 443 (standard)

3. The Blue Pill also uses a https call to https://www.ntppool.org to determine if it can reach the internet, so if that is not possible.

4. The blue Pill also needs to have access to network time via NTP, otherwise it might fail to validate the authenticity of update.
