After: We continue investigating login failures affecting some DXP environments. Affected applications may receive a certificate trust error when connecting to our login service. Affected customers cannot log in to the CMS management interface and are currently unable to create or edit content.
The issue appears to affect applications running on older OS images and .NET versions earlier than .NET 8. Applications on .NET 8 or later seems not impacted based on the reports. Restarting the web application does not resolve the issue.
Our engineering teams are working on a service-side resolution. Impacted regions are still being confirmed.
We will continue to provide further updates.
