Client does not work if db is behind reverse proxy

[TheCodeCaptain]

We have the influx db behind a caddy reverse proxy.
Port 8086 will be served via https://IP-ADDRESS/influxdb
This works fine with rest clients like eg. postman or bruno, they use the /influxdb.
But the cli client seems to forget the /influxdb, so it does not get a response from the influxdb, but from the reverse proxy.
See screenshot from bruno rest client, cli client with http and cli client with https.
