:::tip
**Tip:** Use **Ctrl+F** (Windows) or **Cmd+F** (Mac) to search for your exact error message.

:::

## Replace the URL

**Error message:** It looks like something is wrong with the URL in the post, which prevented it from being published. Please remove the URL and add it back, ensuring it includes either "https://" or "www."

**Why this happens:** Bluesky rejects link previews when the URL is missing its scheme (`https://` or `www.`). Remove the URL from the post, then re-add it with `https://` (or `www.`) at the start.

**What to do:** Remove the URL from the post and re-add it, making sure it begins with https:// or www.
