Hi all,
I’m getting a 502 gateway error for my collector’s tracking pixel URL, and I’m getting this error from the app:
ERROR com.snowplowanalytics.snowplow.collectors.scalastream.KafkaCollector$ - REST interface could not be bound to 0.0.0.0:80
I am only seeing this issue after upgrading the collector from v0.9.0 to v0.13.0 (when I switch back to 0.9.0, everything works). I copied over the relevant configs to the config.hocon.
Here’s my current config.hocon:

Here’s my dockerfile:
# Instructions here https://github.com/snowplow/snowplow-docker
FROM snowplow-docker-registry.bintray.io/snowplow/scala-stream-collector-kafka:0.13.0
# Move over configs
COPY config/config.hocon /var/snowplow/config/config.hocon
# Set a custom CMD to add the necessary docker run configs
CMD [ "--config", "/var/snowplow/config/config.hocon" ]
Does anyone have any ideas about what I could change?
