Quick answer
Viewer: click Watch on YouTube. Site owner: embed using Share > Embed, don’t open the embed link directly (that causes error 153), make sure your site sends an HTTP Referer, and allowlist youtube.com (and youtube-nocookie.com) on your firewall. Creator: turn embedding on in YouTube Studio > Content > Details > Show more > Allow embedding.
Does this match what you see?
- The embedded video shows “Video unavailable” or “Watch on YouTube”.
- You see error 153 in the player.
- An embedded playlist skips some videos.
- The video plays on youtube.com but not on another site.

Why this happens: the possible causes
Why an embedded video won’t play, per YouTube.
| Cause | Who fixes it |
|---|---|
| Embedding turned off by the creator | The creator |
| Video is age-restricted | No one: watch on YouTube |
| Error 153: no HTTP Referer sent | The website owner |
| Private video in a playlist | The creator (or share it with you) |
| Firewall blocks youtube.com | Your network administrator |

YouTube says playback is blocked with error 153 when no HTTP Referer is sent.
Try these 60-second checks first
- Try the video on youtube.com: if it plays there, the problem is the embed.
How to fix it, step by step
Work through these in order. They start with the quickest, safest checks and only move to steps that sign you out or remove data later.
Fix 1: Viewers: watch it on YouTube

Fix 2: Site owners: embed it the way YouTube expects
YouTube’s embed steps, and the network requirement.
Computer (browser)
- On a computer, open the video or playlist, click Share > Embed, and copy the HTML code into your page.
- Network administrators must allowlist youtube.com (and youtube-nocookie.com if you use privacy-enhanced mode).
- Is your site or app aimed at children? YouTube says you must self-designate it, which turns off personalized ads and some player features.
Did it work? The embedded video plays on your page.
Did Fix 2 solve it?
Great, you fixed it with Fix 2. Tell us it worked, or bookmark this page in case it happens again.
Fix 3: Creators: turn embedding on (or off)
YouTube says creators control whether a video can be embedded.
Computer (browser)
- Sign in to YouTube Studio and select Content.
- Next to the video, select Details > Show more.
- Check (or uncheck) Allow embedding, then save.
Did it work? The video plays when embedded.
Did Fix 3 solve it?
Great, you fixed it with Fix 3. Tell us it worked, or bookmark this page in case it happens again.
Error 153
YouTube says error 153 appears when a request has no HTTP Referer, so playback is blocked. Viewers can still click Watch on YouTube. It typically happens when someone opens the embed link directly (for example, in the address bar) instead of on a web page. Site owners fix it by sending an HTTP Referer with their requests; YouTube points to its developer documentation for details.
Privacy-enhanced mode and embed options
- Privacy-enhanced mode: change the embed domain from youtube.com to youtube-nocookie.com. YouTube says views then don’t affect the viewer’s YouTube recommendations, and ads are non-personalized. Websites only.
- Start time: add ?start= and the time in seconds.
- Autoplay: add &autoplay=1 after the video ID. YouTube says autoplayed embeds don’t count as views.
- Captions on by default: add &cc_load_policy=1 (and &cc_lang_pref= with a two-letter language code).
Videos missing from an embedded playlist
YouTube says videos may not appear if the uploader turned off embedding, they’re age-restricted, or they’re private (unless shared with you). For best results, include only public videos that allow embedding.
How to know it worked
- The video plays on the website, or you know why it can’t.
Still not working? Your next steps
- Video won’t play on YouTube either? See YouTube videos not playing. Plays on youtube.com but not an older app or device? See older devices.

YouTube says it appears when no HTTP Referer is sent, often from opening the embed link directly. Viewers can click Watch on YouTube; site owners should send a referrer.
Why does an embedded YouTube video say Watch on YouTube?
YouTube’s help lists embedding turned off, age restriction, and a missing HTTP Referer (error 153) as reasons.
