Grafana / Influx data cleared after awhile

I have set up home assistant to feed into influxdb and am using Grafana to make dashboards. I had already set up a few dashboards in Grafana for my Zabbix monitoring and those have always worked great.
I set up a a new dashboard for home assistant stats. Things like the number of plex streams, how much data has been downloaded from sabnzb in the month. That seemed to go smoothly. By the end of yesterday I would get n/a instead of a value for items coming from Home Assistant. If I fired up a plex stream then the stream would show up in the dashboard.

Does home assistant just stop sending status to influxdb and flush the old data? Did I set something up incorrectly?

Seems like the connection to grafana died? Influxdb is holding the retention days, hassio has no control over the database. It can only insert sensor data. Die you check your configs? Ssl maybe?
