# Why Did My License Stop Working?

**Question:** Why did my license key suddenly stop working?

**Answer:**

## AWS License

If you're using an EC2 instance with an AWS license and your license has stopped working, it may be due to a security group blocking access to the licensing systems. Refer to our troubleshooting guide:

- [AWS License](https://openvpn.net/as-docs/aws-license-troubleshooting.md)

## Subscription or fixed license

If you purchased a subscription or fixed license from our website and it suddenly stopped functioning, it could be due to one of two reasons:

1. **Expired License:** The license may have expired. Check the expiration.
2. **Hardware/Software Changes:** Significant changes to your hardware or software configuration might have caused the licensing system to recognize your system as different. This can invalidate a fixed license.
