If users receive a message there are no available licenses for a domain, there are two likely reasons for this:
* No licenses have been allocated to the customer domain
* Not enough licenses have been allocated to the customer domain

For information about TruGrid licensing, please refer to [this document](/en/article/how-does-trugrid-licensing-work-1jimogp/).

To remediate this, please add sufficient licenses to the domain.
