Originally built internally to protect ngrok.com from malicious traffic, it's now available to all users. Unlike deny or custom-response, which return status codes and optional bodies, close-connection simply drops the connection, useful for avoiding unwanted billed endpoint hours from unwanted traffic. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What does the close-connection action do in ngrok Traffic Policy? Close-connection is a Traffic Policy action that terminates a connection to an ngrok endpoint outright, without sending any response code or body. It can run during either the on_http_request or on_tcp_connect phases and is useful for blocking unwanted traffic before it counts toward billed active endpoint hours, since no response is returned to the client. _Teams filtering unwanted traffic at the edge can compare gateway actions like this one via daily.dev._ ### What is the difference between close-connection and deny in ngrok Traffic Policy? Deny and custom-response send a status code back to the client (deny defaults to 403 and is customizable, while custom-response lets you set both status code and body), whereas close-connection sends nothing and simply drops the connection. Use close-connection when providing a reason for rejection is unnecessary and you just want to shut the connection down. _Developers deciding between gateway rejection strategies can track these comparisons on daily.dev._ --- Tags: [#security](https://daily.dev/tags/security), [#devtools](https://daily.dev/tags/devtools), [#api-gateway](https://daily.dev/tags/api-gateway) [View this post on daily.dev](https://daily.dev/posts/terminate-connections-with-close-connection-3mtlgaeja) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Terminate connections with close-connection","url":"https://daily.dev/posts/terminate-connections-with-close-connection-3mtlgaeja","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/terminate-connections-with-close-connection-3mtlgaeja"},"datePublished":"2026-08-23T07:21:17.305Z","dateModified":"2026-08-23T07:29:32.533Z","description":"Ngrok has added a new close-connection action to its Traffic Policy engine, letting users terminate connections to their endpoints during on_http_request or...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/65f1611d679b55e81844a67131b245aa?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/65f1611d679b55e81844a67131b245aa?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"ngrok Blog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"ngrok Blog","logo":"https://media.daily.dev/image/upload/s--718XXxvE--/f_auto,q_auto/v1787469610/logos/ngrok?_a=BAMAMicg0","url":"https://daily.dev/sources/ngrok"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/terminate-connections-with-close-connection-3mtlgaeja","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security,devtools,api-gateway","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"ngrok Blog","item":"https://daily.dev/sources/ngrok"},{"@type":"ListItem","position":3,"name":"Terminate connections with close-connection"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/terminate-connections-with-close-connection-3mtlgaeja#faq","mainEntity":[{"@type":"Question","name":"What does the close-connection action do in ngrok Traffic Policy?","acceptedAnswer":{"@type":"Answer","text":"Close-connection is a Traffic Policy action that terminates a connection to an ngrok endpoint outright, without sending any response code or body.
