AWS multichain network, "Couldn't connect to the seed node" error

0 votes

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?

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..
