Hello Akash Gondalia,
Thank you for posting your question in the Microsoft Q&A forum.
The error indicates that your bot’s authentication is failing because the client secret for the associated Azure AD app (ID: 95100867-313a-46aa-a475-aaa45fccc6d2) has expired. Since you cannot locate the app registration in the Azure portal even as a Global Admin, the app may have been deleted or is hidden due to tenant restrictions or ownership issues.
First, verify if the app exists by running az ad app show --id 95100867-313a-46aa-a475-aaa45fccc6d2 in Azure CLI. If it’s missing, the bot’s service principal may still linger check Enterprise Applications with the same ID and reassign ownership if needed. If the app is truly gone, you must recreate the bot registration with a new App ID and update all configurations.
To prevent future issues, switch to certificate-based authentication (recommended for production bots) or ensure secrets are rotated before expiry. If the app exists but remains inaccessible, Microsoft Support may assist in recovering it.
