CERN Certificates for influxdb on RPI

As I try to connect to the influxdb instance I get the following warning:

/usr/lib/python3/dist-packages/urllib3/ InsecureRequestWarning: Unverified HTTPS request is being made to host ‘’. Adding certificate verification is strongly advised. See: Advanced Usage - urllib3 2.0.0.dev0 documentation
Traceback (most recent call last):

File “/home/hgsensor/.local/lib/python3.9/site-packages/influxdb/”, line 378, in request
raise InfluxDBClientError(err_msg, response.status_code)

And error:
influxdb.exceptions.InfluxDBClientError: 404: {“error”:“database not found: “hgcal_si_clean_room_monitor””}
From this document I assume that they are connected: InfluxDB - Database on demand User Guide
I have downloaded the CERN Certificates and installed them like this:

  1. To add:
  2. Copy your CA to dir /usr/local/share/ca-certificates/
  3. Use command: sudo cp foo.crt /usr/local/share/ca-certificates/foo.crt
  4. Update the CA store: sudo update-ca-certificates

I work on Ubuntu 20.04.3 LTS
But I still get the message.
