Hi,
Based on the screenshot, your computer doesn't meet that requirement, but it doesn't show which requirement failed.
If your organization uses Company Portal, open it, select your device, and check its compliance status. Follow any listed instructions, then check the status again.
If no details are available, contact your organisation's IT team and send them this screenshot plus the information under More details. They need to verify your device’s registration and compliance status and the policy blocking your VPN sign-in.
