### Remarks

Examples of system errors include failure to resolve a DNS entry, a socket error or a redirect limit being exceeded. When this property returns `true`, the [UnityWebRequest.error](/engine/6000.6/script-reference/unityengine/networking/unitywebrequest/error.md) property will contain a human-readable string describing the error.

**Note:** Error-type server return codes, such as 404/Not Found and 500/Internal Server Error, are reflected in the [UnityWebRequest.isHttpError](/engine/6000.6/script-reference/unityengine/networking/unitywebrequest/ishttperror.md) property, not the [UnityWebRequest.isNetworkError](/engine/6000.6/script-reference/unityengine/networking/unitywebrequest/isnetworkerror.md) property.
