Why has the certificate of the repository https://repos.influxdata.com an issuer name of cloudflaressl?

Fehl:5 InfluxData - Package Repository stable InRelease
Certificate verification failed: The certificate is NOT trusted. The certificate issuer is unknown. Could not handshake: Error in the certificate verification. [IP: 104.21.37.224 443]

The reason for “certificate issuer is unknown” was, that the ca-certificate for “GTS Root R4” was disabled in my Ubuntu.
