Hi all, we have a couple of agents that don't use authentication, and are embedded on some internal websites . They stopped working yesterday, and are coming up with the message below (The agent is not available right now) when trying to access the agent, no changes have been made to the agents or Power Platform settings etc, and they have been working fine for several months.

Just wondering if anyone else has hit this issue or might know what the issue is? I have tried enabling authentication and then published it to Microsoft 365, and the agent worked via Copilot Chat. I spotted the new preview setting "Authentication for agents" in Power Platform admin centre and checked the setting for the Environment that the Copilot agent is in, it was originally set to Require Entra authentication, I have now set this to “No authentication” but the same issue is still occurring.

Not having much luck with Microsoft support so far.

The agent is not available right now
