Before trying the solutions below, check your internet connection and note that a quick restart of your system can also help if the error is temporary.
1. Remove Ad-Blocking Extensions
Ad-blocking or tracker-blocking extensions are the primary reason behind this error. In recent updates, YouTube now actively detects these tools and prevents videos from playing if they are installed. Simply disabling the extension will not work, as YouTube can still detect its presence. The only reliable solution is to remove the extension completely.
2. Switch to Incognito/Private Mode
Using a private browsing window disables extensions and does not carry over your logged-in accounts or stored data. This creates a clean browsing session that often allows YouTube to work without triggering the error. If these solutions do not fix the issue, the problem may be linked to browser misconfigurations. Several users have reported that switching browsers (for example, using Firefox instead of Chrome, or vice versa) resolved the error. However, if you prefer not to change browsers just for YouTube, the best option is to contact the official YouTube support team for further assistance.
