Failed to load GeoGebra Geometry: ${err?.message || err}

Error message

Failed to load GeoGebra Geometry: ${err?.message || err}

What it means

ensureApplet() navigates to the GeoGebra Geometry URL when the current page is not already there. If page.goto() fails (network error, DNS failure, TLS problem, timeout, offline), it throws CommandExecutionError 'Failed to load GeoGebra Geometry: ...' wrapping the navigation error.

Solutions

1. Confirm network access by loading https://www.geogebra.org/geometry in a normal browser.
2. Check proxy/firewall/VPN settings and allow geogebra.org; if behind a proxy, configure the browser launch with the proxy flag.
3. Retry after a transient outage — wrap in a retry with backoff.
4. If offline use is required, pre-load the GeoGebra applet or serve it locally and point GEOGEBRA_URL at the local copy.

Example fix

// before
await goto(GEOGEBRA_URL); // net::ERR_NAME_NOT_RESOLVED
// after
try { await goto(GEOGEBRA_URL); } catch (e) { await new Promise(r => setTimeout(r, 2000)); await goto(GEOGEBRA_URL); }

const reachable = await fetch('https://www.geogebra.org', { method: 'HEAD' }).then(r => r.ok).catch(() => false);
if (!reachable) throw new Error('geogebra.org unreachable — check network/proxy');

null

try { await ensureApplet(page); } catch (e) { if (String(e.message).includes('Failed to load')) { await sleep(2000); await ensureApplet(page); } else throw e; }

When it happens

Trigger: Calling any geometry tool while offline, geogebra.org unreachable (DNS/proxy/firewall), HTTPS certificate problems, or goto timeout because the page hangs — any err thrown by page.goto(GEOGEBRA_URL).

Common situations: Corporate proxies blocking geogebra.org, sandboxed/air-gapped environments, captive portals, transient network outages, or headless environments missing CA certificates.
