<p>Make sure your firewall allows outgoing connections on port 7874 or 6874 on testnet. </p>

<p>You can also try to invoke the getPeers API from the <a href="http://localhost:7876/test" rel="nofollow noreferrer">http://localhost:7876/test</a> page with "active" set to "true". You should see a list of IPs your connected to, if you don't see anything, double check your 7874 port. </p>
