iOS Outlook/Teams cannot sign in my account since Microsoft Defender Endpoint is not reachable

I am trying to login to my Microsoft account for Outlook and Teams. I have the VPN on and running with connect on demand enabled. I am logged in to Microsoft Defender and "Everything looks good" with device protection active and network protection secured. I am running iOS version 26.4 (current latest as of 4/5/2026). I am restarted, updated both teams and outlook. I have restarted my iOS device twice. I've restarted the VPN twice and tried signing out of Outlook and Teams and re-signing in. None of these actions seem to resolve the Microsoft Defender Endpoint being reachable. Thank you for any advice or guidance.
