No data on all widgets

[peatonet]

I fixed the 502 error by changing the influxdb host to the IP of my device on the 'docker-speedtest-grafana/docker/grafana/provisioning/datasources/influxdb.yml' file. However, now all the widgets are showing me the "No data" message.

Could you please suggest some tests or troubleshooting steps in order to check why is happening this issue?

Thanks in advance.
