403 error when accessing stream output

[ellisonbg]

When the frontend hits the stream API, we are seeing a 403:

    tornado.web.HTTPError: HTTP 403: Forbidden

Interestingly, the call is successful and the data shows up in the frontend.

Just saw this as well: ``` 403 POST /api/security/csp-report ***@***.***) 2.50ms referer=None ``` Looks like it is related to CSP stuff.
