AWS multichain network Couldn t connect to the seed node error

Question

I am new to multichain. I am using 2 instances on AWS EC2. I have created a blockchain using one instance.. 

>multichaind secondChain -daemon

MultiChain Core Daemon build 1.0 alpha 27 protocol 10007

MultiChain server starting
Looking for genesis block...
Genesis block found

Other nodes can connect to this node using:
multichaind secondChain@XXX.XX.X.XX:XXXX

Node started

But i am not able to connect to blockchain from the 2nd instance. i am getting the following error:

>multichaind secondChain@XXX.XX.X.XX:XXXX

MultiChain Core Daemon build 1.0 alpha 27 protocol 10007

Retrieving blockchain parameters from the seed node XXX.XX.X.XX:XXXX ...
Error: Couldn't connect to the seed node XXX.XX.X.XX on port XXXX - please check multichaind is running at that address and that your firewall settings allow incoming connections.

I think this has something to do with the network because my commands seems to right. How to solve this problem?

Answer 1

The error says "please check multichaind is running at that address and that your firewall settings allow incoming connection"

So allow connections in your firewall and check your port settings..
