Title: Having trouble connecting to peers Post by: Elwar on August 07, 2018, 11:32:12 PM I just got bitcoinj up and running. I have been able to run the example Kit program a few times which takes a long time before it connects to enough peers to download the latest block but occasionally it does, then ends as it is supposed to.
I'm trying it on testnet. I have run it for an hour and it won't connect to any peers. Is this just me or is it common? I get warning messages such as this: [NioClientManager] INFO org.bitcoinj.core.PeerGroup - [46.19.33.249]:18333: Peer died (0 connected, 8 pending, 12 max) [PeerGroup Thread] INFO org.bitcoinj.core.PeerGroup - Waiting 10000 msec before next connect attempt to [178.21.118.174]:18333 [NioClientManager] WARN org.bitcoinj.net.NioClientManager - Failed to connect with exception: java.net.ConnectException: Connection refused: no further information java.net.ConnectException: Connection refused: no further information ....

Does your FW forward packets sent to the corresponding ports?
