Channel connectors not loading

Same here. 

The error seems to be related to the webapp itself. 

Some console errors are:

[Error] Refused to connect to https://login.microsoftonline.com/common/oauth2/authorize?...._0&x-client-ver=7.5.1.0 because it does not appear in the connect-src directive of the Content Security Policy.
