💡 Quick Answer
If you see the error “AnkiWeb encountered a problem. Please try again in a few minutes,” it usually means the Anki servers are temporarily overloaded or your network is blocking the connection. To fix it: wait 15-30 minutes, switch to a different network (like a mobile hotspot), or restart Anki with add-ons disabled (holding down the Shift key). If the issue persists, go to Tools > Check Database to repair your local collection.
For medical students, language learners, and lifelong students, Anki is a lifesaver. But there is nothing more panic-inducing than finishing a grueling 500-card review session only to hit “Sync” and see the dreaded message: “AnkiWeb encountered a problem. Please try again in a few minutes.”
This error halts your progress across your devices (Anki desktop, AnkiDroid, and AnkiMobile) and leaves your local database out of sync with the cloud. Fortunately, resolving this issue is usually straightforward. In this guide, we will walk you through the most effective troubleshooting steps to get your flashcards syncing smoothly again.
Why is AnkiWeb Failing to Sync?
Before diving into the fixes, it helps to understand what triggers this connection failure. Based on official Anki documentation, this error typically stems from one of the following factors:
- Server Overload/Maintenance: AnkiWeb is a free service hosting millions of users. During peak hours, the server might throttle connections.
- Strict Firewalls or VPNs: Corporate or school Wi-Fi networks, as well as aggressive antivirus software, often block the specific ports Anki uses to connect to
ankiweb.net. - Corrupt Database: An inconsistency in your local deck collection can cause the server to reject your sync request.
- Add-on Conflicts: Outdated third-party add-ons can interfere with Anki’s background sync processes.

Step-by-Step Troubleshooting Guide
Follow these steps in order to diagnose and resolve the issue. We recommend starting with the easiest solutions first.
| Step | Action Required | Time Estimate |
|---|---|---|
| 1. The Waiting Game | Wait 15-30 minutes and try syncing again. | 15+ Mins |
| 2. Network Swap | Disconnect from Wi-Fi and use a mobile hotspot. | 2 Mins |
| 3. Check Database | Navigate to Tools > Check Database. | 1 Min |
| 4. Safe Mode | Restart Anki while holding the Shift key. | 3 Mins |
1. Switch Networks and Check Firewalls
A common culprit for the “connection timed out” or server problem error is network filtering. If you are on a university or hospital Wi-Fi, they might block unknown data transfers. Try connecting your laptop to your smartphone’s mobile hotspot. If the sync works immediately, the problem is your local Wi-Fi router or firewall. You can find more details on adding Anki to your firewall exceptions on the Official Anki FAQ page.
2. Perform a Database Check
Sometimes, closing Anki forcefully or experiencing a computer crash can leave your flashcard database in an inconsistent state. The server will reject the sync to prevent corruption.
- Open Anki on your desktop.
- Click on Tools in the top menu bar.
- Select Check Database.
- Wait for the prompt that says “Database rebuilt and optimized.” Try syncing again.
3. Start Anki in Safe Mode (Disable Add-ons)
Add-ons make Anki incredibly powerful, but they are known to cause backend bugs. Close Anki completely. Then, hold down the Shift key on your keyboard and double-click the Anki icon to open it. Keep holding Shift until the app fully loads. This starts Anki without any add-ons. If you can sync successfully in Safe Mode, one of your add-ons is the culprit. Disable them one by one to find the problem.
📌 TL;DR Summary
- Don’t panic: Your data is saved locally. You won’t lose your progress.
- Wait it out: The error is often just a temporary AnkiWeb server timeout.
- Change connections: Move from your school/work Wi-Fi to a mobile hotspot to bypass firewalls.
- Optimize: Use Tools > Check Database to clean up any corrupt cards.
- Update: Ensure you are running the latest stable release from the official Anki website.
