<p>I'd like to access the EC2 instance that installed bitcoin mainnet node.
I've found out that I need to open the port 8332 of instance from the <a href="https://bitcoin.stackexchange.com/questions/41800/how-to-connect-bitcoind-mainnet-node-on-aws-ec2-by-using-rpcjson">question</a>, but I have not idea how to do it.</p>

<p>I tried to add port 8332 on the security group, however I cannot select 8332 port, only can select 80.</p>

<p>Could you tell me how to open the port and access bitcoin node?</p>

<p><strong>Update</strong></p>

<p>I've set port as the attached picture.
However, it returned the following error.</p>

<p><strong>Connection refused - connect(2) for 'publicIP address' port 8332</strong></p>

<p>It means that I still cannot connect the instance? or I've already connect the instance, but returned error by another reason?</p>

Could you tell me how to open the port and access bitcoin node?

**Update**

I've set port as the attached picture.
However, it returned the following error.

**Connection refused - connect(2) for 'publicIP address' port 8332**

It means that I still cannot connect the instance? or I've already connect the instance, but returned error by another reason?
