- Plesk Onyx for Linux
Unable to add a new subscription on the Management Node in Plesk MultiServer in Plesk > Subscriptions > Add new:
PLESK_ERROR: Internal error: no service node specified.
This issue is caused by the Plesk bug: #EXTPMS-1173. It is going to be fixed in the future Plesk Updates.
As a workaround re-save nodes in Management node > Nodes > node_name > (Do not change anything) > Save.
If there are more than 1 Service Nodes, repeat re-saving for all of them.
