Your Vimeo embed stopped working.
Three documented causes, quickest to check first.

When you switch a video to Unlisted, Vimeo adds a privacy hash to its URL, and its help centre says the hash must be included for embeds and sharing to work. An embed code copied before the switch, or rebuilt by hand, often leaves it out. Vimeo’s parameter guide also says that for Unlisted URLs such as ?h=913062c8ff, every other parameter must come after the hash, joined with &, so check the order as well as the hash itself.

Fix: copy a new embed code from the video’s share options and replace the old one on your site. If you add options by hand, put them after ?h=....

The second version of this cause is domain-level privacy. If you limited where the video may be embedded, Vimeo’s embed FAQ says you must allow your website’s domain. If your site recently moved to a new domain, check that the new one is on the list.

Fix: add the exact domain your page is served from to the video’s embed settings. If the video is Private, Vimeo’s advice is to use Unlisted instead, because Private videos only play for team members.

If the player says the video does not exist, Vimeo has a separate troubleshooting article for that message.

When a paid plan lapses to Vimeo Free, Vimeo’s help centre describes a chain of changes that reach your website directly:

• Videos beyond the Free plan’s 1 GB are restricted, and the most recent uploads are the first to be restricted. That is why your newest embed often breaks first while older ones keep playing.
• Restricted videos cannot be played, edited or downloaded, and their clip pages and embeds stop working.
• Password, Unlisted and Embed only videos are switched to Private, which only team members can see.
• Domain-level embed privacy is changed to Nowhere. You must set it to Anywhere to embed again.
• Player customizations go back to the default.

A lapse to the legacy Basic plan follows the same newest-first rule with a 5GB cap, and restricted embeds stop working there too.

Fix: renew the plan, or bring the library under the cap. Vimeo says archived videos are restored if you upgrade within a year of lapsing. After renewing, check each video’s privacy setting and set domain-level privacy back from Nowhere, because those changes are not described as being undone for you. Restricted videos cannot be downloaded, so if you plan to leave, renew first and take your files out while the plan is active. The cancellation guide covers the order to do this in.

Vimeo’s bandwidth policy for self-serve plans sets a threshold of 2TB per month. It says that going over it does not normally stop streaming. Outreach starts when an account has gone over 2TB in a month at least twice in the past 12 months, or over 10TB once. Automated notices come first, then Vimeo’s team may get in touch.

From there you have seven days to reach a resolution, with no account changes during that time. If nothing is resolved, the account is at risk of a temporary suspension. Suspended videos stop playing wherever they are distributed or embedded. You still have access to the videos, but your website does not.

The newer Creator plan lists 1TB of monthly bandwidth, and Vimeo says that plan is being rolled out gradually. The bandwidth article does not say how the 1TB figure is enforced, so check the plan and notices on your own account.

Fix: answer the outreach inside the seven days and agree a resolution with Vimeo. Our bandwidth guide explains how to estimate your traffic before that conversation.

The other two causes have equivalents here, and it is fairer to say so. Privacy still decides what an embed will play, and a plan still caps storage. The table sets out what changes and what does not.

Two points to check before you move. First, storage: Hot capacity is released after the archive copy is verified and the library change is saved. Archived films must be restored before streaming, embedding or review. Second, playback quality depends on the viewer. Browser playback uses your uploaded export without another platform re-encode. Codec, device and connection requirements still apply. If your site’s visitors are on slow connections, export a file sized for them.

The embed takes eight optional parameters: autoplay (which always starts muted), muted, loop, title, playbtn, accent colour, controls (hover or none) and background (transparent or a six-digit hex colour). Settings saved in your dashboard apply first, and URL parameters override them. The embed-only guide shows how to keep a film off the public web while it plays on your site.
