A null-routed IP or hosting-side downtime is not something you can confirm or resolve yourself. If you suspect either, skip ahead and contact Hostinger support<\/a> directly so the team can confirm the status and give you an update, rather than continuing through the remaining steps below.<\/p> NOTE<\/strong><\/p> Visit Cloudflare’s status page<\/a> to see if Cloudflare is reporting an active incident. If so, the 520 error is on their side, and you only need to wait for it to resolve.<\/p> A broken or conflicting .htaccess file can prevent your origin server from responding correctly.<\/p> Cloudflare Development Mode temporarily bypasses Cloudflare’s cache so you can see your origin server’s actual response. Turn this on while troubleshooting, then turn it off once the issue is resolved. See How to enable Cloudflare development mode for a website on Hostinger<\/a>.<\/p> If your hosting resources are overloaded, your origin server may not respond in time.<\/p> If the steps above do not resolve the error, check for a mismatch between your Cloudflare SSL\/TLS encryption mode and your origin’s actual SSL setup.<\/p> Open your Cloudflare dashboard, then go to SSL\/TLS<\/strong> > Overview<\/strong> for your domain. Confirm which encryption mode is selected: Off, Flexible, Full, <\/strong>or Full (strict).<\/strong><\/p> If you are using Full or Full (strict) and seeing intermittent 520 errors, switch to Flexible<\/strong> as a test. If the error stops, your origin SSL setup is the cause.<\/p> NOTE<\/strong><\/p> For broader Cloudflare SSL issues not specific to a 520 error, see Troubleshooting Cloudflare Universal SSL at Hostinger<\/a>, Introduction to SSL at Hostinger,<\/a> and Troubleshooting 5xx Errors at Hostinger<\/a>.<\/p> If none of the steps above resolve the error, contact Hostinger support<\/a> with what you have already checked, so the team can investigate further. For general 520 troubleshooting beyond these Hostinger-specific steps, see How to Fix Error 520<\/a>.<\/p> Once you find and resolve the specific cause, your website loads normally through Cloudflare again.<\/p>\n","protected":false},"excerpt":{"rendered":" Fix a Cloudflare 520 error at Hostinger by ruling out common causes, from a null-routed IP to a broken .htaccess file.<\/p>\n","protected":false},"author":594,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"include_on_kodee":true,"footnotes":""},"categories":[180],"tags":[],"class_list":["post-19315","post","type-post","status-publish","format-standard","hentry","category-website-troubleshooting"],"hreflangs":[],"include_on_kodee":true,"_links":{"self":[{"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/posts\/19315","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/users\/594"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/comments?post=19315"}],"version-history":[{"count":3,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/posts\/19315\/revisions"}],"predecessor-version":[{"id":19324,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/posts\/19315\/revisions\/19324"}],"wp:attachment":[{"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/media?parent=19315"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/categories?post=19315"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/tags?post=19315"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n
