1. No peers to connect to
If your wallet shows zero connections, it cannot download anything. This often happens when the built-in list of starting nodes in an old wallet is out of date, so the addresses it tries no longer answer.

Your Auroracoin wallet is stuck. The progress bar has not moved for hours, the block count is frozen, or the corner of the window says "0 active connections". This guide explains what syncing means, why older Auroracoin wallets get stuck and what you can safely do about it.
First, the reassuring part: a wallet that is not syncing has not lost your coins. Your AUR is recorded on the Auroracoin blockchain. Your wallet just cannot see the latest part of it yet.
A desktop wallet needs to know the current state of the blockchain to show your correct balance and to send payments. To get there, it connects to other computers on the Auroracoin network, called peers or nodes, and downloads the blocks it is missing.
A full-node wallet such as the legacy Auroracoin Core client downloads and checks the whole blockchain on your computer. That is very secure, but slow, and it depends on finding healthy peers. If the wallet cannot find peers, or the peers it finds are on an old version of the chain, syncing stops.
If your wallet shows zero connections, it cannot download anything. This often happens when the built-in list of starting nodes in an old wallet is out of date, so the addresses it tries no longer answer.
Security software sometimes blocks a wallet from talking to the network, especially after a Windows or macOS update. The wallet opens normally but never connects.
Blockchains depend on timestamps. If your system date or time is far off, the wallet may reject valid blocks or peers. This is easy to miss and easy to fix.
After a network upgrade, an older wallet version may keep following blocks the rest of the network no longer accepts. It looks stuck, or it shows transactions that never confirm. We cover this in detail in our chain split guide.
If your computer shut down suddenly, or the disk filled up while syncing, the downloaded blockchain data can become damaged. The wallet may stop at the same block every time it starts.
Work through these steps in order. Stop as soon as your wallet starts moving again.
Close the wallet completely. Make a copy of your wallet file (in older Auroracoin Core wallets this is the file called wallet.dat) or confirm that your recovery words are written down. Store the copy on a USB drive kept somewhere safe. Do not skip this step.
Make sure you are online and that your computer's date, time and time zone are set automatically. Restart the wallet and wait a few minutes.
Open your firewall or antivirus settings and check whether the wallet app is blocked. Allow it to connect, then restart the wallet. Only do this for wallet software you downloaded from the official source.
If the connection count is above zero and the block number is slowly rising, the wallet is working. A full-node wallet catching up after a long break can take a long time. Leave it running.
If the wallet always stops at the same point, the local blockchain data may be damaged. Older wallets keep this data in folders separate from your wallet file. Rebuilding means removing only that downloaded chain data so the wallet downloads it again. Never remove your wallet file. If you are not completely sure which file is which, do not delete anything and move on to Step 6.
If your old wallet still will not sync, the software itself may be the problem. Your coins are not tied to it: your wallet file or recovery words can be opened in a newer wallet.
Aurora Wallet is the new official desktop wallet for Auroracoin. It is designed with the sync problems above in mind:
These are design goals of the new wallet, not claims that every past problem is solved. Release details are listed on the Updates page.
Is my money gone if my wallet won't sync? No. Your AUR is stored on the blockchain. As long as you keep your wallet file or recovery words, you can access your coins again in any compatible wallet.
How long should syncing take? It depends on how far behind your wallet is, your internet speed and the type of wallet. A full-node wallet that has been closed for a long time can take many hours. If the block number is rising, let it run.
Should I delete my wallet and reinstall? Never delete your wallet file. Reinstalling the app is fine, but back up your wallet file first and keep it safe.
Someone online offered to fix my sync for me. Is that safe? No. Never share your recovery words, private keys or wallet file with anyone. Real support will never ask for them.
Where can I see if my coins are still there? You can look up your Auroracoin address on a public block explorer. This only reads public data and does not need your keys. Never enter your recovery words on any website.
