Can't open the webcore app


After installing the app (following the directions on the wiki) and enabling oauth in the IDE, i get this error message when opening the app. I’ve tried removing the app and repo completely and trying again to no avail. Any help?

Edit: It seems to be one of my devices that is causing this when I add it to the list of allowed devices, it breaks the app. I’ll have to go through them one by one to find the culprit…
