I have timeout trying to connect my Zilla deployment to Open Telemetry

[vordimous]

DNS and networking have been confirmed to be correct, but Zilla still can't send any data and logs this error.

Zilla log:

Warning: The otlp exporter could not successfully push data to the specified endpoint for 300 seconds.

zilla.yaml telemetry config:
