When you tap a custom feed in Bluesky, the app sometimes displays a red banner that reads “Failed to fetch.” The feed stays blank and you cannot scroll through its posts. This error typically occurs because the feed’s algorithm server is unreachable or because the feed’s URL contains a syntax error that Bluesky cannot parse.
The root cause is often a temporary outage on the feed host’s side, a broken link in the feed’s source code, or a network restriction on your device. This article explains why the error happens and provides exact steps to fix it on both the app and desktop versions of Bluesky.
Key Takeaways: Fixing the Bluesky Custom Feed Fetch Error
- Reload the feed by pulling down: A simple refresh often resolves temporary server timeouts.
- Remove and re-add the feed: Deleting the feed from your saved list and adding it again forces a fresh URL request.
- Check the feed’s source URL in a browser: If the feed’s algorithm endpoint returns a 404 or 500 error, the feed is broken and must be reported to its creator.
Why Bluesky Shows ‘Failed to Fetch’ on Custom Feeds
Custom feeds in Bluesky are not hosted by Bluesky itself. Each feed is powered by an external algorithm server, typically running on a service like Fly.io, Railway, or a personal server. When you open a custom feed, the Bluesky app sends a request to the feed’s defined URL. If that server is offline, overloaded, or returns an unexpected response, the app displays “Failed to fetch.”
Another common cause is a malformed feed URL. Feed creators define the URL inside the feed’s AT Protocol record. If the URL contains a typo, an expired domain, or a missing path segment, the Bluesky client cannot reach the server. Network-level issues such as a VPN blocking the feed server or a strict firewall on a corporate network can also trigger the same error.
Server-Side vs Client-Side Causes
Server-side causes include the algorithm server crashing, exceeding its rate limit, or being taken down by the creator. Client-side causes include a corrupted local cache, an outdated app version, or a DNS resolution failure on your device. Distinguishing between these two categories helps you decide whether to wait for the feed creator to fix the server or to troubleshoot your own setup.
Steps to Fix ‘Failed to Fetch’ on a Bluesky Custom Feed
Follow these steps in order. Test the feed after each step before moving to the next one.
- Refresh the feed by pulling down
Open the custom feed tab. Place your finger at the top of the screen and pull downward until the loading spinner appears. Release your finger. If the feed loads after the refresh, the error was a temporary server timeout. On desktop, press F5 or click the refresh icon in the browser toolbar. - Close and reopen the Bluesky app
Force quit the app completely. On iPhone, swipe up from the bottom and swipe the Bluesky card off the screen. On Android, open the recent apps menu and swipe Bluesky away. On desktop, close the browser tab. Wait 10 seconds, then open Bluesky again and navigate to the feed. - Remove the feed from your saved list and add it again
Go to your saved feeds by tapping the hashtag icon or the Feeds tab. Tap the three-dot menu next to the problematic feed and select Remove feed or Unpin. Then search for the feed again using its name or creator handle and pin it back. This clears any cached metadata and forces the app to request the feed URL from scratch. - Check the feed’s source URL in a browser
Ask the feed creator for the feed’s AT Protocol record or look up the feed on a directory like blueskyfeeds.com. Copy the feed URL. Open a new browser tab and paste the URL. If the browser shows a 404, 500, or connection refused error, the feed server is down. Contact the feed creator and report the issue. - Disable VPN or proxy temporarily
If you use a VPN or a corporate proxy, turn it off and try loading the feed again. Some feed servers block traffic from known VPN IP ranges. After disabling the VPN, refresh the feed. If it loads, add an exception for the feed’s domain in your VPN settings. - Update Bluesky to the latest version
On iOS, open the App Store, search for Bluesky, and tap Update. On Android, open Google Play, search for Bluesky, and tap Update. On desktop, the web app updates automatically when you refresh the page. An outdated client may have bugs that prevent certain feed URLs from being parsed correctly. - Clear the Bluesky app cache
On Android, go to Settings > Apps > Bluesky > Storage > Clear Cache. On iOS, there is no system-level cache clear tool. Instead, uninstall and reinstall the app. On desktop, clear your browser cache for the Bluesky domain. A corrupted cache can store a stale response that blocks the new fetch request. - Try a different network
Switch from Wi-Fi to mobile data or connect to a different Wi-Fi network. If the feed loads on the alternative network, your original network is blocking the feed server. This is common on school, office, or public Wi-Fi networks that filter certain ports or domains.
If Bluesky Still Shows the Error After All Fixes
The feed works for other users but not for you
Ask a friend or post in the Bluesky community to confirm whether the feed loads for them. If it loads for others, the problem is on your side. Repeat steps 5 through 8 above. Also check whether you are logged into the correct account. A second account on the same device may have different saved feeds.
No custom feeds load on your account
If every custom feed shows “Failed to fetch,” your Bluesky account may have a corrupted session token. Go to Settings > Account > App Passwords and revoke any existing app passwords. Then log out of your account and log back in. This generates a fresh session token and clears any broken authentication state.
The feed creator published an update that broke the feed
Feed creators sometimes change the algorithm server URL without updating the AT Protocol record. The old URL becomes a dead link. Check the feed creator’s Bluesky profile or website for an announcement about server migration. If you cannot find any information, unpin the feed and look for an alternative feed that provides similar content.
Comparison: Custom Feed Fetch Errors vs Native Feed Errors
| Item | Custom Feed Error | Native Feed Error |
|---|---|---|
| Error message | “Failed to fetch” | “Something went wrong” or blank timeline |
| Root cause | External algorithm server is down or unreachable | Bluesky’s internal API or database is overloaded |
| Scope | Affects only one specific feed | Affects all feeds including Following and Discover |
| Fix time | Depends on feed creator’s server uptime | Usually resolved within minutes by Bluesky engineers |
| User action | Refresh, re-add feed, or contact creator | Wait and check Bluesky status page |
Native feed errors are rare and typically affect all users simultaneously. Custom feed fetch errors are isolated to one feed and often point to a problem with the feed’s external server.
You can now diagnose and fix the “Failed to fetch” error on any Bluesky custom feed. Start with a simple refresh, then remove and re-add the feed. If the problem persists, check the feed’s source URL in a browser to determine whether the server is down. For persistent issues on your device, clear the app cache or switch networks.
