Outage Details

We are currently aware of an issue that is impacting users logging into web-based applications from both Chrome and Edge version 136 that causes a blank Duo Prompt to appear. We are working on a fix for this issue urgently and hope to provide an update soon. As a workaround, if users upgrade their browser to a newer version, authentication will work as normal, which is also a recommended best practice for security as well. Additionally, users logging into Epic Hyperdrive may also experience this issue when attempting to log in, and our fix will also apply to that application once released. As a temporary workaround, you can downgrade Hyperdrive to 100.2506.3, which will move to a lower Chromium Version (134.0.6998.205) and no longer see the issue. As soon as our fix has been released, we'll provide an update as soon as possible.
