Cloudflare can’t connect to your origin. Check your server/hosting for any problems. The IP address for your wildcard record is not responding on ports 80 and 443 if that’s also where your site is hosted… https://cf.sjr.dev/tools/check?60c5bbaa1143496ab4ebf57a6ab45f54#dns
You can set the Cloudflare DNS record to “DNS only”, or “pause” Cloudflare, so requests go direct to the origin for debugging, then re-enable Cloudlfare when the problem is fixed.
