Fans watching the 2026 World Cup online are facing an unexpected opponent: their VPN's built-in ad blocker. When using ad-funded streaming services like ITVX, the ad blocker stops the entire broadcast instead of just the commercials. This happens because of server-side ad insertion (SSAI), which merges ads and live content into a single stream from the same server. When the ad blocker detects a portion of an ad, it cannot distinguish it from the match footage, so it blocks the entire video. The result is a black screen or freeze right at the crucial moment.
How SSAI causes conflicts with ad blockers
Streaming services increasingly use server-side ad insertion to deliver seamless viewing and circumvent traditional ad blockers. With SSAI, ads are injected directly into the video stream at the server level, before reaching the user's browser. This means the ad blocker cannot identify a third-party domain for the ads and therefore cannot filter them selectively. However, when the VPN's ad blocker tries to block ad-related requests, it ends up halting all communication with the streaming server, causing the video to crash. This issue has become especially noticeable during the 2026 World Cup, with numerous users reporting freezes during round of 16 matches.

Quick fix: disable the VPN's ad blocker
The simplest solution is to manually turn off the ad blocking feature within your VPN. Most providers, such as Norton VPN, offer a dedicated toggle. For Norton, simply go to settings and disable Ad Tracker Blocking from the VPN Preferences tab. Once disabled, streaming resumes smoothly. For those reluctant to fully remove protection, there is a technical workaround: during playback, open your browser's developer tools, monitor the Network tab, and identify the blocked tracking domain. Then add that URL to your ad blocker's whitelist. Windscribe, with its R.O.B.E.R.T tool, allows creating custom site-specific whitelisting rules, so you can keep blocking other ads while allowing the stream.

Tips for uninterrupted streaming
To enjoy the England vs Mexico match without buffering or crashes, check your VPN settings before kickoff. If you use an ad-free service like iPlayer, you are safe. Otherwise, temporarily disable the ad blocker. Norton VPN offers a 60-day money-back guarantee and download speeds up to 1010 Mbps, ideal for 4K streaming. For an alternative, consider Windscribe, which handles whitelisting more granularly. For broader context, read our related article on the UK generational smoking ban and technology lessons.
