What is causing the error message "POST https://rum-http-intake.logs.datadoghq.com/v1/input/pub9238a331d14b5f49624bb5e93b1bbd64?ddsource=browser&ddtags=sdk_version%3A3.6.12%2Cenv%3Aprod%2Cservice%3AWebflow-Dashboard%2Cversion%3Amain-7aa45cc013078e2b9def076ddf9bb0d99acbf3a5&batch_time=1687869247112 net::ERR_BLOCKED_BY_CLIENT" when trying to edit a component in Webflow that contains an embed element?
TL;DR
- Error is caused by an ad or privacy browser extension blocking Webflow’s Datadog analytics request.
- To resolve, disable extensions, use Incognito mode, or whitelist
rum-http-intake.logs.datadoghq.com; the error doesn’t impact site functionality.
You're seeing the “ERR_BLOCKED_BY_CLIENT” error because a browser extension — most commonly an ad blocker or privacy-based extension — is preventing a network request to Datadog, Webflow's third-party logging service.
1. Understand the Error Source
- URL involved:
rum-http-intake.logs.datadoghq.comis part of Datadog's Real User Monitoring service. - Error Message:
net::ERR_BLOCKED_BY_CLIENTindicates a local client-side block, not a Webflow server or configuration issue. - When it Happens: Often triggered when interacting with Webflow's Designer or editing components that include
<embed>elements, which might cause more tracking events or logs to be transmitted.
2. Identify the Blocking Extension
- Check for extensions like AdBlock, uBlock Origin, Ghostery, or Privacy Badger.
- These tools may incorrectly flag telemetry or analytics calls as tracking attempts and block them.
3. Test Without Extensions
- Open the Webflow Designer in an Incognito/Private window with all extensions disabled.
- Alternatively, temporarily disable privacy-related extensions and reload the Designer.
4. Whitelist Datadog’s Domains (Optional)
In your ad blocker or privacy extension settings, allow or whitelist the domain:
rum-http-intake.logs.datadoghq.comThis will prevent future blocks to Datadog’s monitoring scripts but can reduce anonymity depending on your tool’s configuration.
5. Confirm It's Not Blocking Webflow Features
- This Datadog call is not critical to Webflow’s editing or publishing workflow.
- It’s used for analytics and performance monitoring within the Dashboard or Designer.
- The error doesn’t affect your project or site functionality unless a security extension breaks other scripts.
Summary
The error is caused by a browser extension (likely an ad or privacy blocker) intercepting and blocking Webflow's analytics call to Datadog. This doesn’t affect your Webflow project’s functionality. Disable the extension or whitelist datadoghq.com if you want to eliminate the warning.
