Frequently Asked Questions

Why does Clash of Clans keep going out of sync during attacks?
Out of sync errors during attacks usually occur due to poor internet connection, outdated game version, or temporary server issues. The game requires constant data synchronization during battles, so any interruption can cause desync.
Will I lose my attack if I get an out of sync error?
Unfortunately, yes. When an out of sync error occurs during an attack, the battle is typically lost and you'll lose your troops and any loot bonus. However, you won't lose trophies if the error occurs early in the attack.
Can out of sync errors be caused by using VPN?
Yes, VPNs can cause out of sync errors because they can create routing delays and make it appear you're connecting from a different location than expected, causing server communication issues.
How do I prevent Clash of Clans sync errors in the future?
Maintain a stable internet connection with good speed, keep the game updated, avoid using VPNs while playing, and restart the app if you notice any lag or connection issues before starting important attacks.
Does clearing game cache delete my village progress?
No, clearing cache only removes temporary files and won't delete your village progress. However, you may need to re-download some game assets, and any saved replays might be lost.
