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 question, but I have not idea how to do it.
I tried to add port 8332 on the security group, however I cannot select 8332 port, only can select 80.
Could you tell me how to open the port and access bitcoin node?
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?
