InfluxDB access tokens may come out of sync with startup.conf

[PeterHawk]

Running the test_server.py after following instructions resulted in errors:

write_api.write(bucket, org, point)

(Pdb) config["influxdb"]

-> write_api.write(bucket, org, point)

Cause was the use of an invalid access token and fixed by updating startup.conf with the valid one found in InfluxDB->Tokens

[clagms]

This is now documented as a common problem, and the solution has been described:

To fix open the InfluxDB web management page, go to InfluxDB->Tokens and generate a new token. Then update [startup.conf](../../../startup.conf) with the new token.
