My Wallet is not connecting to Bitcoin network. The last time it was running the block took over two weeks and when it arrived just over 70% it stopped working. Now I try each day to get the wallet to connect to get in sync again but no luck yet. What can I do? I downloaded Bitcoin Core - Wallet (testnet) and the bottom message Connecting to peers states 6 years and 31 weeks behind. I installed my original wallet in 2011
First, don't use testnet but mainnet.
If your firewall is correctly set and you have no warning rom your anti-virus, this is probably your database or an corrupted index (when the wallet stopped to work).
The best is to save your wallet and begining again the blockchain download (delete the database and the indexes).
