<p>If you're on Amazon AWS try this:</p>

<pre><code>setsebool -P httpd_can_network_connect 1
</code></pre>

<p>I had the same problem and it took me hours to figure out that the server was blocking connections. I thought it wasn't the problem because my AWS security group allowed it. But apparently the server was blocking it directly.</p>

<p>For anyone trying to connect locally to a wallet:</p>

<p>I managed to get mine working locally by changing <code>rpcallowip</code> and <code>rpcconnect</code> from <code>127.0.0.1</code> to my actual local I.P. address (e.g. <code>192.168.0.2</code>), seems that by using default <code>localhost</code> or <code>127.0.0.1</code> does not always work.</p>

This is incredibly insecure. You should only allow the IPs you will be connecting from.

this allowed me to test locally after hours of trying specific ips.  Will not use for production though.

Can you add the verbose option and tell us what is says?  
 `-v / --verbose`

add this to bitcoin.conf

```
rpcallowip=0.0.0.0/0

```

allow all ip
