Configuration like below.

  1. Openssl

openssl req -x509 -nodes -newkey rsa:2048 -keyout influxdb-selfsigned.key -out influxdb-selfsigned.crt -days <Number_of_Days>

Common Name: PC Name

  1. Influxdb3.exe serve –node-ind host01 –object-store file –data-dir ~/.influxdb3_data –tls-cert= influxdb-selfsigned.crt tls-key=influxdb-selfsigned.key

URL: https://localhost:8181
Use Postman ping the url https://localhost:8181/ping with token can return the correct result (200 & the current version 3.0.1)

But use the .NetCore SDK to query data will return the SSL or certificate error.
Could any one can help?
