Choosing Faculty not possible because list is empty #383

Closed sockeqwe closed 8 years ago

sockeqwe commented 8 years ago

Steps to reproduce:

  1. Install the app from play store
  2. StartUp-Wizard appears tum1
  3. Click on "Please Choose your faculty" but the list of faculties is empty: tum2

Device: Nexus 6 running Android 23

kordianbruck commented 8 years ago

Was a Internet connection present during setup? The list is fetched from an API on first load, so a connection is required...

sockeqwe commented 8 years ago

yes, active internet connection. I just have uninstalled and installed it yet again to verify that a internet connection is active. Still same issue.

nilstk commented 8 years ago

Similar topic, different issue: Upon creation of a question and selection of the faculties (scroll down the list to select all), the app crashes always

sockeqwe commented 8 years ago

It's a backend issue!

Yea, sessions spammed the inodes on the server and it couldn't create any new sessions. This is now fixed.
