Unsure why this differs from the previous value, but this is the
organization name actually used by the running database. Output from
the container:
2023-01-11T19:22:41Z E! [outputs.influxdb_v2] Failed to write metric to system_metrics (will be dropped: 404 Not Found): not found: organization name "Netz39" not found

HTTPS ingress configuration
HTTPS ingress is controlled by the server holmium and forwarded to the configured servers.
To set up a new HTTPS vhost, the following steps need to be taken:
- Select a domain (for internal services we use sub-domains of
.n39.eu). - Create an external CNAME from this domain to
dyndns.n39.eu. - Create an internal DNS entry in the Descartes DNS config. This is usually an alias on an existing server.
- Add the entry to the holmium playbook.
- Set up Dehydrated and vhost on the target host, e.g. using
setup_http_site_proxy.
Do not forget to execute all playbooks with relevant changes.
