Hi all, I'm trying to get scheduled slack notifications to work (I am using firefox and geckodriver in the config) and I am continuously getting\n```Task email_reports.send[ea45abef-b657-4e74-ace5-7a008d2bc38c] raised unexpected: WebDriverException('connection refused', None, None)\n...\nselenium selenium.common.exceptions.WebDriverException: Message: connection refused```\nI have a feeling it might be to do with `WEBDRIVER_BASEURL=<http://mysite.com>` or possibly the google oauth? How does it authenticate to through the headless browser to send? :thinking_face:
