Unable to launch influxDB with https

Hello there !

I installed InfluxDB freshly, I got a LetEncrypt certificate, I tried to set it according to the doc, and I could not start InfluxDB without really more details.

InfluxDB 1.7.4 on Debian 9.8.

> Feb 21 09:38:45 mon systemd[1]: influxdb.service: Start request repeated too quickly.
> Feb 21 09:38:45 mon systemd[1]: Failed to start InfluxDB is an open-source, distributed, time series database.
> Feb 21 09:38:45 mon systemd[1]: influxdb.service: Unit entered failed state.
> Feb 21 09:38:45 mon systemd[1]: influxdb.service: Failed with result 'exit-code'.

Well apparently he does not have sufficient rights on the certificate > https://pastebin.com/raw/XtzDwUVf

The rights to apply since the doc should be enough no ?
