CHT Tutorial Contacts + User Management Part 1 user authentication

@Esther_Moturi - two follow up questions:

  1. are you running this in an Incognito tab and logging in as offline user? If yes, try running in a non-incognito tab.
  2. if you continue to get the Could not resolve host error, consider adding a hard coded /etc/hosts entry per these instructions.

Let us know if either of those helps!
