Cannot get the app to work on localhost

Even after getting past #2 and #3 I'm stuck with this error in the web console:

ERROR Error: oidcInfo
    at authn.service.ts:35:13
    at Generator.next (<anonymous>)
    at asyncGeneratorStep (asyncToGenerator.js:3:1)
    at _next (asyncToGenerator.js:25:1)

    at Zone.run (zone.js:134:43)
    at zone.js:1275:36
    at _ZoneDelegate.invokeTask (zone.js:406:31)

Any advice?
