Why do I see more log entries on fly-metrics.net than in the NATS stream?

When I subscribe to NATS via vector.dev using the same parameters as fly-log-shipper, it seems, I receive only a subset of the logs, I see on the Grafana dashboard (victoriametrics).

Why is that and can I change that?

I am subscribing to the logs.> topic and I tried different queue groups thinking, I might have a clash with the default queues.

OK, deploying this on fly, the output looks a lot different than from localhost using wireguard… Any idea why that might be the case?
