Best answer

Inside folder multichain-other there is a folder with the name of your chain. In your case it is "node1".

Inside this folder there is a file: multichain.conf

Edit this file and set port and rpc port. Example:


Then instead of:

multichain-cli -datadir=.multichain-other node1


multichain-cli -datadir=.multichain-other -port=10255 -rpcport=10254  node1

Yes.. I followed same procedure but still i am getting same error
Can you copy-paste the command you are trying? maybe there is a typo.
-rpcport must be unique so also be sure that each instance is running on different rpcport.

Correct example would be something like:
multichain-cli -datadir=multichain-other -rpcport=10254 node1 getinfo
error is solved... Thank you
