Error message

Request resulted in an unexpected StatusCode [{0}]

What it means

Thrown by RssImportBaseParser.PreProcess when a base RSS import-list request responds with a non-200 status. It is an ImportListException carrying the ImportListResponse, raised before the feed XML is loaded. This is the generic RSS import base (distinct from the RSSImport/RSSImportParser variant) used by other RSS-style lists.

Solutions

1. Open the configured RSS URL from the Radarr host and confirm HTTP 200 + XML.
2. Fix the URL/auth in the import-list settings.
3. Disable the list if the source is permanently gone.

var resp = await httpClient.GetAsync(new HttpRequest(rssSettings.Url));
if (resp.HttpResponse.StatusCode != HttpStatusCode.OK) { /* fix URL/auth, do not sync */ }

static bool IsListStatusError(Exception ex) => ex is ImportListException ile && ile.Response?.HttpResponse?.StatusCode != HttpStatusCode.OK;

try { parser.ParseResponse(importResponse); }
catch (ImportListException ex) { importListStatusService.RecordFailure(definition, ex.Message); }

When it happens

Trigger: An RSS base import-list fetch returns a non-200 status from importListResponse.HttpResponse.StatusCode — 404 wrong URL, 401/403 auth, 5xx server down, or a redirect to a non-feed location.

Common situations: Misconfigured RSS feed URL, feed moved/decommissioned, requires auth not supplied, or the source site is down.
