Hi Alex Beat,
Thank you for reaching out.
The error you're encountering usually means the sign‑in request cannot complete securely. In most cases, this is related to required security or network conditions not being met, even when account details are correct.
Please try these possible checking steps to resolve this:
1, Check secure connection (TLS) settings - Microsoft sign‑in requires modern encryption.
- Press Windows + R, type
inetcpl.cpl, press Enter - Open Advanced > Security, ensure:
- Use TLS 1.2: checked
- Use TLS 1.3 (experimental): checked (if available)
- TLS 1.0 / 1.1: unchecked
- Select OK and restart the PC
2, Disable network filtering temporarily - Sign‑in may fail if traffic is filtered or intercepted.
- Turn off any VPN
- Remove any configured proxy (Settings > Network & Internet > Proxy)
- If using custom DNS or network filtering, switch temporarily to automatic DNS
- Restart the PC and try signing in again
3, Verify the account works outside Windows apps
- Sign in to Microsoft account using a web browser
- If sign‑in works online, the account itself is confirmed active and accessible
4, Repair Windows sign‑in components
- Open Command Prompt (Admin)
- Run:
sfc /scannow - Then run:
DISM /Online /Cleanup-Image /RestoreHealth - Restart the PC
You’ve already completed many advanced troubleshooting steps, which rules out common causes. Following the steps above helps ensure your system meets current sign‑in requirements and confirms where the issue is occurring.
