Hi,
I am receiving this error. Any idea why I am receiving this and how to resolve it ?

INFO:snowplow_tracker.emitters:Attempting to send 1 events

This means that the tracker isn’t able to access the internet over the host you’ve provided (localhost:9090). Is the collector running and accessible (e.g., via a browser?)
