How to specify InfluxDB Certificate Authority?

I’ve got my InfluxDB connection up and running with self signed SSL cert, but setting “verify_ssl: true” breaks the connection.
And this gets logged:
Http: TLS handshake error from 192.168.50.41:36832: remote error: tls: unknown certificate authority.

How do I specify the CA to trust for InfluxDB connections?
I’ve seen that some components allow you to specify “verify_ssl: /pki/myCA.crt” but this doesn’t seam to work.
