Stderr is
An error occurred while updating domain settings: Cannot set limit 'disk_space_soft' value to '-1': Unable to allocate the required amount of resources (Unlimited Disk space). Only 90 GB Disk space are available.

Cause

Reseller is lacking resources.

Resellers have their own resources they can sell, and for this particular reseller overselling is not allowed, therefore it is not possible to increase the disk limit for his subscription.
