"Page not found" for a reader
Do the checks in this order.
| Cause | How to check | Fix | Documented by Anthropic |
|---|---|---|---|
| The sender shared the artifact inside an organization, and the reader is not a member | Ask the sender which audience they chose. "Only people invited" and "Anyone at [organization]" need a signed-in member | The sender invites the reader by email (beta), or publishes the HTML on a different host | Yes |
| The reader uses a different Claude account | Tell the reader to open the link in a private window, then sign in with the invited address | Sign in with the invited address | Yes. An invitation is for one address |
| An Owner turned off External sharing | Ask an Owner to check Organization settings, Artifacts. When the setting is off, existing public links stop working | The Owner turns it on, or allows that one artifact | Yes |
| An Owner turned off outside email invitations | Same settings page. When the setting is off, people who are already invited cannot open the artifact | The Owner turns it on | Yes |
| The invitation expired | Pending invitations expire after 30 days. Accepted invitations do not expire | The sender sends a new invitation | Yes |
| The sender unpublished or deleted the artifact | The sender checks the Artifacts tab | Unpublishing a legacy chat artifact is permanent. Make a new artifact | Yes |
| The text of the screen | Users report "Page not found" for several of the causes above | None | No |
"Cannot republish" or "the link changed"
| Cause | What happens | Fix |
|---|---|---|
| Someone unpublished a legacy chat artifact | You cannot publish it again. Unpublishing also deletes its stored data | Create a new artifact. The old link stays broken |
| A new Claude Code session did not get the old URL | The session creates a new artifact | Give Claude the URL, or attach the artifact with /artifacts. Then ask for the update |
| An editor published a newer version | Claude Code refuses a publish that it built on the older copy | Claude merges its changes onto the newer version and publishes again |
| The session is not signed in | Claude Code prints Artifacts need a claude.ai login | Sign in with /login |
| Plan mode, or a publish that declares capabilities | Claude Code asks before it publishes | Approve the prompt |
| The page is too large | The publish or the share fails on large pages | Read Claude artifact too large to share |
Stop depending on the share state
A link on claude.ai depends on three things: the audience setting, the policy of the organization and the publish state of the artifact. Each one can change after you send the link. For a page that readers must open again and again, publish the HTML to Display.
- Add Display from claude.ai/directory/display.
- Tell Claude: "Publish this artifact to Display as a Company page."
- Send the Display link. Readers sign in with their company email. For a client, publish the page as Private and invite the client by email. The client enters a one-time password and can view the page. Clients cannot comment yet.
- To change the page, tell Claude: "Update the page at the same link." The link stays the same, and paid plans keep the earlier versions.
When the link is on your own host, a change to the Claude sharing settings cannot break it. Read How to share a Claude artifact privately.
FAQ
Can I publish an unpublished Claude artifact again?
Not a legacy chat artifact. Anthropic says that you cannot publish it again. Make a new artifact.
Does unpublishing delete data?
Yes, for a legacy chat artifact that used storage. Unpublishing permanently deletes its personal and shared storage data.
Why does my link work for me but not for my client?
You are a member of the organization. Your client is not. Read the first table.
Why did a public link stop working when nobody changed the artifact?
An Owner possibly turned off External sharing. Existing public links stop working until an Owner turns it on again.
Does a Display link break if I cancel my Claude plan?
No. Display stores the page, and the URL continues to work.
