My configuration:
influxdb:
api_version: 2
port: 8086
...
With the following log error:
2021-02-03 15:07:45 ERROR (SyncWorker_19) [homeassistant.components.influxdb] Cannot connect to InfluxDB due to 'HTTPConnectionPool(host='us-west-2-1.aws.cloud2.influxdata.com', port=8086): Max retries exceeded with url: /api/v2/write?org=c3448531f156e78b&bucket=home_assistant&precision=ns (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f70dc1988b0>: Failed to establish a new connection: [Errno 110] Connection timed out'))'. Please check that the provided connection details (host, port, etc.) are correct and that your InfluxDB server is running and accessible. Retrying in 60 seconds.
It appears to me that the default configuration for InfluxDB version 2 Host is set to: us-west-2-1.aws.cloud2.influxdata.com and I believe the default port is also set to:80, not localhost on 8086 as I expected.
Not sure if this is what is intended? But anyways this is a heads up…
