Error "Due to technical limitations, we are unable to remove domain.zone at this time"

Please be informed that to assist Registrars in controlling the Add Grace Period deletions under their Registrar Account, Registrar has restricted Add Grace Period deletions across the system.

For example, deletions beyond 8% of net gTLD registrations in a month (total registrations less domain names deleted during AGP) will not be allowed. You can confirm the same by referring to the knowledgebase article given below: https://cp.regway.com/kb/answer/1416

Furthermore, if you see the error: "Error: “Due to technical limitations, we are unable to remove...", this means that the daily "domain tasting" deletion limit set by the TLD registry has already been exhausted and you can try again next days.
