Hello @Christina Pardali,
Thank you for posting your query on Microsoft Q&A.
Based on the error message, it seems that authentication for your Azure tenant has been temporarily disabled due to a recent security incident. As discussed over Teams chat, to re-enable or deauthenticate the tenant, please follow the steps I shared with you during our conversation.
Since you are an internal employee, the process for deauthenticating tenants differs slightly compared to external users. Please ensure you follow the internal guidelines accordingly. Let me know if you need further assistance!
