What it means

fetchStatusData GETs <baseURL>/api/status-page/<slug> and treats any response that is not HTTP 200 as an error, returning the raw resp.Status string. The uptime-kuma status page data is essential to the widget, so failure here fails the refresh.

Solutions

1. Open <baseURL>/api/status-page/<slug> in a browser and fix baseURL/slug to match
2. Enable/create the status page in Uptime Kuma (Status Pages settings) and copy its exact slug
3. Check reverse proxy/port config if the browser test 404s despite a correct slug
4. Confirm Uptime Kuma is running and reachable

Example fix

// before
baseURL := "http://localhost:3001"
slug := "My Status" // slug is actually "mystatus"
// after
baseURL := "http://localhost:3001"
slug := "mystatus"

u := fmt.Sprintf("%s/api/status-page/%s", strings.TrimRight(baseURL, "/"), slug)
resp, err := http.Get(u)
if err == nil && resp.StatusCode == 200 { _ = resp.Body.Close(); /* config OK */ }

data, err := fetchStatusData(baseURL, slug)
if err != nil {
    log.Printf("uptimekuma status page unreachable (%v); keeping last data", err)
    return
}

When it happens

Trigger: Uptime Kuma returning non-200 on the status-page endpoint: wrong baseURL, wrong/unknown slug, status page disabled or not created in Uptime Kuma, or an auth-protected status page answering 401/403.

Common situations: Status page not enabled in Uptime Kuma settings; slug in config not matching the slug set on the status page; widget pointed at the wrong port or reverse-proxy path; Uptime Kuma down/restarting.
