Outage Details

We have identified the communication issue between the Duo prompt and the Device Health Application for Chromium-based browsers on macOS and Windows, which will make it so that users running the latest version of the browsers will be prompted to install the Device Health Application even when it is already installed, and will not allow authentication, if your Policy settings require it. The issue is caused by a new Chrome certificate store and acceptable Certificate Authorities. Google is rolling out this specific change to their certificate store as a rolling release, so not everyone on the latest version of Chrome has this change yet. Other browsers, such as Firefox and Safari, are currently unaffected. All other services are fully operational and customers who do not use the Device Health Application are unaffected. We are currently working on rolling out a fix for all customers.
