Can't reach datadog agent

Hey folks! I'm trying to launch a datadog agent via docker on Railway. It works when I run it locally on my mac, but I can't seem to make requests to it when I launch it on railway. Is there something special I need to do with exposing ports? Here's the docker file:

FROM datadog/agent

ENV DD_APM_NON_LOCAL_TRAFFIC=true
ENV DD_DOGSTATSD_NON_LOCAL_TRAFFIC=true

ARG DD_API_KEY
ARG DD_SITE
ARG DD_HOSTNAME

EXPOSE 8125/udp
EXPOSE 8126/udp

FROM datadog/agent

ENV DD_APM_NON_LOCAL_TRAFFIC=true
ENV DD_DOGSTATSD_NON_LOCAL_TRAFFIC=true

ARG DD_API_KEY
ARG DD_SITE
ARG DD_HOSTNAME

EXPOSE 8125/udp
EXPOSE 8126/udp

I can confirm the agent starts just fine and seems to be checking for metrics. I just can't call it from the outside. Been trying like this (again, works locally):

echo -n "rainmaker.backend.express.router.response_code.200:55|g|#shell" | nc -4u -w0 datadog-agent-production-2d86.up.railway.app 8125

for the time being you can only run http services, railway does not support TCP/UDP and you can only access the services externally from port 443
