<summary>What is the relationship of an Offline licensing instance and the gracePeriodDays &#x26; ignoreServerExceptions parameters? How and when do these parameters interact with an Offline licensing instance?</summary>

The behavior depends on how the offline mode is configured:

#### Offline Mode Enabled

* No online license checks are made.
* `gracePeriodDays` and `ignoreServerExceptions` are ignored.
* License validity is checked locally using cryptographic signatures.

#### Offline License Used in Online Mode

* `checkLicense()` calls will still be made.
* `gracePeriodDays` allows server exceptions to be ignored for a limited time.
* If `ignoreServerExceptions` is set to true, server-related exceptions will be ignored indefinitely, and the local license will be used instead.
