127.0.0.1:8080: connect: connection refused #270
Description
Diode version
v0.6.0
Deployment type
docker compose
Deployment type version
Docker Compose version v2.34.0
Diode SDK type
diode-sdk-python
Diode SDK version
v0.4.0
Diode NetBox Plugin version
v0.6.0
NetBox version
v4.2.7
Steps to reproduce
The Netbox and Diode are hosted on the same VM (Ubuntu 22.04.03). The steps taken follow the documentation (https://docs.netboxlabs.com/netbox-discovery/agent/get-started/) with most recent version of Netbox (v4.2.7) and all default values. The Netbox installation is the standard one (https://netboxlabs.com/docs/netbox/en/stable/installation/).

Expected behavior
When running the command;
docker run -v $(pwd):/opt/orb/ -e DIODE_API_KEY=<MY-KEY> netboxlabs/orb-agent:latest run -c /opt/orb/agent.yaml
The connection to the Diode should be sucessfull.
Observed behavior
When running the command;
docker run -v $(pwd):/opt/orb/ -e DIODE_API_KEY=<MY-KEY> netboxlabs/orb-agent:latest run -c /opt/orb/agent.yaml
It gives following error:

I've made sure that API keys are correct and that there is no firwall. When logging to the Netbox UI I see that there is Diode plugin installed with Diode target being "grpc://localhost:8080/diode". Ingestion logs are empty.
