Port 8080 failed: Connection refused

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. Port is open in the firewall

Any ideas???

Does Grafana or its agent (I don’t know about Grafana) try to connect from another host using the address 127.0.0.1?
