A Zoom cloud recording share link most often stops working because the link was replaced, not because the recording is gone. Zoom issues a new URL whenever the host changes who the recording is shared with — so the address you already emailed out is no longer the address that opens the file.
That one behaviour accounts for a lot of "it worked yesterday" reports. The rest come down to an expiry date, an IP restriction, a recording that is still processing, or a file that really was deleted. And for that last case, Zoom's own error text points you at the wrong culprit.
What actually breaks the link
Zoom's article on managing and sharing cloud recordings puts the most consequential sentence in a note: "A new, unique cloud recording link is generated when the shared users or groups are changed."
Read that literally. The share URL is bound to the current sharing configuration. Add a group, remove a person, switch the recording from internal to public — and Zoom generates a different link. Whatever is already sitting in an email thread, a calendar invite or a chat message refers to the previous one.
Zoom's note stops there; it does not describe what recipients of the older link see. What it does establish is that the link you sent and the link now on the recording's page are not necessarily the same string — so copy it again before troubleshooting anything else.
The fastest fix, in order
- Re-copy the share link from the Zoom web portal. If anyone touched the sharing list since you sent it, this step alone is the fix.
- Check the expiry date. Zoom's troubleshooting page for missing cloud recordings has a section titled "Cloud recording share link not working", and its first instruction is exactly this: "Check if your recording has an expiry date. If it does, remove the expiry date or extend it."
- Check IP restrictions. The same section adds: "Check if you're blocking certain IP addresses from view your cloud recordings."
Expiry is one of the per-recording sharing options. Zoom describes it as "Set expiration date: Specifies the number of days or a specific date when the link will expire." Because it is set per recording, one dead link while a colleague's link still works is entirely normal — they were configured separately.
The IP check usually traces back to an account-level setting that hosts cannot see. Zoom describes it as: "IP Address Access Control: Only allow specified IP addresses to playback shared cloud recordings. This setting applies to cloud recordings that are shared publicly or to authenticated users." Note the scope in that second sentence — it covers public links and authenticated ones, so signing in is not a workaround. A viewer at home or in another office simply will not be on the list.
The error message that misleads you
If your viewers report this exact string, copy it down before guessing:
"The media could not be loaded, either because the server or network failed or because the format is not supported."
Zoom's recording FAQ attributes it to something entirely unrelated to formats: "The original recording was deleted or in the trash bin. Contact the owner of the recording so they can try to recover the recording from the trash bin."
So the words "format is not supported" are a red herring. Nobody needs to convert, re-encode or update a player. The recording behind the link is missing, and the person who can do something about it is the host, not the viewer. If the file went to the trash rather than being purged, it is usually still retrievable — see how to recover a deleted Zoom cloud recording for what Zoom says is and is not recoverable.
When the link cannot be fixed, send the file itself
Some dead links do not come back. Zoom states that when an account is downgraded to a free plan, "your cloud recordings are set to be deleted after 30 days" unless the account resubscribes within that window. Deleting a user without transferring their recordings is worse: in Zoom's words, "the recording files bypass the trash folder and are permanently deleted and cannot be recovered."
In those cases, whoever still holds a downloaded MP4 becomes the source of truth. Zoom's page on sharing computer recordings suggests uploading it to a third-party service, naming Dropbox, Box, Google Drive, YouTube and Vimeo. Emailing it is the other option — and there, file size is usually the obstacle.
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
This runs in your browser tab: the file is read from disk, re-encoded locally and handed back to you. Nothing is uploaded, which matters for a recording that was never meant to leave your organisation. For other formats and output sizes, see all Clapr tools or compress video.
One thing that is not an option: Zoom states plainly that "Cloud recordings cannot be embedded on websites, in order to protect the security of the recording." If a link is failing inside an iframe on an intranet page, that is expected behaviour rather than a bug.
Other causes, in rough order of likelihood
- The recording is still processing. Zoom notes: "You can share your recording while it's processing, but viewers will see a message that the recording is processing and won't be able to play the recording." The link is fine; it is early. See Zoom recording stuck on processing for how long Zoom says this should take.
- The recording is being trimmed. Zoom warns that "While content is being trimmed, viewers with access to the recording won't be able to view it," and that "Depending on the length of the recording, it can take about 2 hours to trim a recording." Zoom also notes that when edits fail, "the recording remains in a trimming state."
- It was trimmed already. "If you trim a recording and share the link, viewers can only access the trimmed version, not the full recording, for viewing or downloading."
- A passcode or registration is in the way. Zoom's sharing options include "Passcode: Requires a password for viewing or downloading," and a registration option that "Requires users to enter their name and email address before viewing or downloading the recording."
- The download button is missing rather than the link being broken. Zoom's fix is oddly specific: "Make sure your browser window is set to a minimum width of 1024 pixels. Maximize your browser window and set your monitor resolution to at least 720p (1280 by 720 pixels)."
- Downloads were switched off. Zoom notes that "The recording host may have restricted access to download the recording, meaning you can't download the recording even if you use a tool to search the URL for a download." Admins have a matching control, "Cloud recording downloads", and a separate one that can lock out hosts themselves: "Prevent hosts from accessing their cloud recordings."
- The account uses on-prem cloud recording. Zoom: "If this account enabled on-prem cloud recording, cloud recordings are not accessible in the Zoom web portal. Contact your Zoom admin for help."
How to tell it worked
Re-send the freshly copied link and have one recipient — not the host — open it. If the goal is downloading rather than viewing, have them open it in a maximised window, since Zoom ties the download button's visibility to a browser window at least 1024 pixels wide. If they can play it and nobody touches the sharing list afterwards, the link is stable.
FAQ
Why did my Zoom recording link stop working right after I shared it with more people? Because changing the audience changes the link. Zoom states that "A new, unique cloud recording link is generated when the shared users or groups are changed." Copy the current link from the recording's page and resend it.
Do Zoom cloud recording links expire by default? Expiry is a per-recording setting: "Set expiration date: Specifies the number of days or a specific date when the link will expire." The Zoom pages quoted here do not state a default value, so open the recording's sharing options to see what yours is set to, or check the official documentation.
Viewers see "format is not supported" — do I need to convert the recording? No. Zoom attributes that exact message to a recording that "was deleted or in the trash bin," and tells viewers to contact the owner so the file can be recovered from the trash. Converting the file would not help even if you had it.
Why can my viewers watch the recording but not download it? Either downloads were restricted, or the browser window is too narrow to show the button. Zoom says a host can restrict downloading so "you can't download the recording even if you use a tool to search the URL for a download," and separately advises a browser window of at least 1024 pixels wide.
Can I embed a Zoom cloud recording in a webpage instead of sharing a link? No. Zoom states that "Cloud recordings cannot be embedded on websites, in order to protect the security of the recording." Download the MP4 and host it elsewhere if you need an embed.
