Error updating from NOAA: {error}

Error message

Error updating from NOAA: {error}

What it means

UpdateFailed(f'Error updating from NOAA: {error}') from the aurora forecast coordinator when aiohttp raises a ClientError during api.get_forecast_data — any transport-level HTTP failure (DNS failure, connection refused/reset, TLS error, non-connection HTTPException from aiohttp). The coordinator logs it and schedules a retry; sensors keep last-known values.

Solutions

1. Verify outbound internet and DNS from the HA host (curl the NOAA forecast URL)
2. If a proxy is configured, add NOAA domains to allowed destinations
3. For transient failures, rely on the coordinator's automatic retry
4. Check NOAA SWPC service status if failures persist

try:
    await coordinator.async_refresh()
except UpdateFailed as err:
    if str(err).startswith("Error updating from NOAA"):
        _LOGGER.info("NOAA fetch failed; will retry next interval")

When it happens

Trigger: GET to the NOAA SWPC aurora forecast service failing at the network layer: no internet, DNS for the NOAA host failing, connection reset, proxy rejecting the request.

Common situations: Temporary internet outages; DNS filtering/blocking the NOAA domain; HA running behind a proxy that drops the request; NOAA service unreachable during incidents.
