Connection refused port 8080

Jitsi meet is working fine so I wanted to use grafana. I installed influxdb & telegraf both are up und running but telegraf status says:
“Error in plugin: [url=http://localhost:8080/colibri/stats]”

“curl -v http://127.0.0.1:8080/colibri/stats” says: connect to 127.0.0.1 port 8080 failed: Connection refused

All config files seem to be ok

Any ideas???
