Failed to fetch data: {response.status}

Error message

Failed to fetch data: {response.status}

What it means

Raised in `afetch_data` of the IMF maritime chokepoint info fetcher when the ArcGIS FeatureServer behind IMF PortWatch returns a non-200 HTTP status for the chokepoints GeoJSON query. Any transport-layer problem surfaces as this single status-code error; the surrounding `except` re-wraps non-OpenBB exceptions into `OpenBBError` as well.

Solutions

1. Retry after a short delay — transient ArcGIS 5xx/429 responses usually clear.
2. Verify the URL still resolves: open the FeatureServer query in a browser or curl and check the JSON envelope.
3. Check ArcGIS Online health / IMF PortWatch status pages for outages.
4. If behind a proxy, ensure aiohttp session honors your proxy env vars and the host is allow-listed.

for attempt in range(3):
    try:
        info = await obb.economy.imf.maritime_chokepoint_info()
        break
    except OpenBBError as e:
        if 'Failed to fetch data' in str(e) and attempt < 2:
            await asyncio.sleep(2 ** attempt)
            continue
        raise

When it happens

Trigger: GET to services9.arcgis.com PortWatch_chokepoints_database FeatureServer returning 4xx/5xx: ArcGIS outage or maintenance, rate limiting (HTTP 429), or a changed/retired service URL after an ArcGIS redesign.

Common situations: Esri ArcGIS Online incidents; corporate proxies or firewalls blocking services9.arcgis.com; the FeatureServer layer ID changing; bursts of requests tripping ArcGIS throttling.
