No need to worry. Due to the distributed nature of the network, it is possible that any given node may go a few days without any relay rewards. Typically a delay in rewards is simply temporary, with rewards increasing again within a week, and continuing to grow over time.
POKT rewards scale with service, not necessarily stake. Since multiple nodes can service multiple sessions, BlockSpaces recommends running multiple nodes to ensure consistent relay rewards.
Support staff sets up and closely monitors each node on the network in identical fashion. For the vast majority of cases, when nodes witness a small delay in rewards, they are in fact healthy, and working fine.
