Error Connexion influxdb datasource on grafana

I'am facing an error every time i open influxdb data source(dashboard:telegraf system metrics)


this problem is faced only with this datasource

Start by reproducing the error when opening the InfluxDB datasource used by the Telegraf system-metrics dashboard, using the linked screenshot as the initial symptom. No source files or tests are named, so trace the datasource-opening path and identify the environment-specific failure. Done means the datasource opens without this error and the behavior is verified.
