Most chronic, site-wide refused-connection problems trace back to a crashed service, a firewall rule, or resource exhaustion \u2014 all preventable with the right hosting setup.<\/p>\n\n\n\n<section class=\"ecr-faq\" style=\"max-width:760px;margin:32px auto;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Helvetica,Arial,sans-serif;color:#1E293B;\">\n  <style>\n    .ecr-faq details{border:1px solid #E2E8F0;border-radius:10px;margin:10px 0;background:#fff;overflow:hidden;}\n    .ecr-faq details[open]{border-color:#BFDBFE;box-shadow:0 1px 4px rgba(37,99,235,.08);}\n    .ecr-faq summary{list-style:none;cursor:pointer;display:flex;align-items:center;gap:12px;padding:16px 18px;font-size:16px;font-weight:600;color:#1E293B;}\n    .ecr-faq summary::-webkit-details-marker{display:none;}\n    .ecr-faq summary .q{flex:0 0 auto;display:inline-flex;align-items:center;justify-content:center;width:24px;height:24px;border-radius:6px;background:#EFF6FF;color:#2563EB;font-weight:800;font-size:14px;}\n    .ecr-faq summary .chev{margin-left:auto;flex:0 0 auto;transition:transform .2s;color:#94A3B8;}\n    .ecr-faq details[open] summary .chev{transform:rotate(180deg);}\n    .ecr-faq .ans{padding:0 18px 16px 54px;font-size:15px;line-height:1.65;color:#475569;}\n  <\/style>\n  <div style=\"font-size:24px;font-weight:800;color:#0F172A;margin:0 0 4px;\">Frequently asked questions<\/div>\n  <p style=\"color:#64748B;font-size:15px;margin:0 0 16px;\">Quick answers about the ERR_CONNECTION_REFUSED error.<\/p>\n  <details>\n    <summary><span class=\"q\">?<\/span>What does ERR_CONNECTION_REFUSED mean?<svg class=\"chev\" width=\"18\" height=\"18\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2.5\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M6 9l6 6 6-6\"\/><\/svg><\/summary>\n    <div class=\"ans\">It means your browser tried to open a connection to the website&#8217;s server and the connection was actively rejected \u2014 usually because the web service is down, the port is closed, a firewall is blocking it, or a setting on your own device (proxy, VPN, DNS) is interfering.<\/div>\n  <\/details>\n  <details>\n    <summary><span class=\"q\">?<\/span>Is it a problem with my computer or the website?<svg class=\"chev\" width=\"18\" height=\"18\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2.5\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M6 9l6 6 6-6\"\/><\/svg><\/summary>\n    <div class=\"ans\">It can be either.
