When I click Sign In for the page https://app.devtest.ringcentral.com/login it spins for a while, then finally lets me enter my credentials. Then it tries to load the page, but keeps spinning again.
I checked the Network log and it is getting a 404 error loading app.config.js with the following details:
Code: NoSuchKey
Message: The specified key does not exist.
