Following a scheduled update on the evening of March 17, an unexpected change in behavior is preventing users who access the Azure portal directly — without first going through Kion — from being able to view their Azure resources or subscriptions
If you are affected, please use the following process:
1.) Sign in to Kion at https://kion.cloud.tamu.edu. 2.) Navigate to your Project and use the Cloud Access buttons to select a role and access Azure. 3.) Continue working in the Azure portal from that Kion-launched session.
While this change was unintended, there is currently no method to revert to the previous behavior, making this a permanent change going forward. Directly logging into the Azure portal without first authenticating through Kion is no longer supported. Kion-initiated Azure sessions will remain active for eight (8) hours.
For assistance, please contact Cloud Operations at cloudops@tamu.edu.
