# Error Code: 0xCAA20003

# **Refresh Token Expired**

## **Error Message**

```plaintext
0xCAA20003 Authorization grant failed
AADSTS700082: The refresh token has expired due to inactivity
```

---

## **Root Cause**

> The **BPRT token (refresh token)** stored in Key Vault is **expired or inactive**.

From the message:

- Token expired due to **inactivity**
- Azure enforces refresh token lifetime rules

---

## **Why does this happen**

Typical scenarios:

- Token generated but **not used for a long period**
- Token rotation has not been done
- Old token still present in Key Vault
- Pool provisioning stopped for weeks/months

👉 Azure invalidates token silently → failure during provisioning

---

## **Resolution**

### Regenerate BPRT token

- Use PowerShell / WCD
- Use the same provisioning account (Conditional Access policy excluded for MFA)

### Update Key Vault

- Replace existing secret value
- Keep the **same secret name**

### Reprovision VM

- Validate join success

---

## **Validation**

- VM provisioning succeeds
- No token errors in logs
- Entra join completes

---

## **Key Takeaway**

> BPRT tokens **expire due to inactivity** — must be rotated proactively.
