Domains and domain subscriptions are terminated ahead of schedule.
Domains are automatically terminated because of their TLD configuration for the domain plug-in under
Top > Service Director > Domain Manager > Plug-ins > Plug-in name > TLDs > TLD in question
Terminate domain at the registrar in 1 days before domain expiration date
As it is stated in Setting Registrar Prices
You can set forced domain termination at a certain period (hours/days) before domain expiration date. This is needed in case an automated renewal is configured to terminate the domain before its automatic renewal takes place.
Reconfigure the plug-in.
