Influx query fails on 1 instance but not another

I have 2 influx instances where a query is working on one instance but not the other.

SELECT mean(“bytes-sent”) AS “mean_bytes-sent” FROM “ME”.“30days”.“CLIENT” WHERE time > now() - 12h GROUP BY time(10s) FILL(null)

I can see the data coming in to both influxes using the logstash client which is how the data is getting into the influxes, but not sure why this query just sits there on 1 instance and works fine on the other. Suggestions?
