Error: Couldn't connect to the seed node

+4 votes

I am new to multichain and I am running multichain using Ubuntu 20.04. Everything is running smoothly, I even connected my blockchain with the multichain explorer 2. The thing is that I can connect to the blockchain from another machine connected to the same LAN, however when I try to connect a node that is connected to a different LAN I get the error "Couldn't connect to the seed node on port 6819 - please check multichaind is running at that address and that your firewall settings allow incoming connections". I have disabled firewall and any kind of antiviruses on both machines. Is it a rule that I can connect to a blockchain if it is connected to the same network that my node is running? Any help regarding this would be tremendously appreciated.

In general, an IP address like is for connecting via the same local network. The server running node will probably have another IP address, which is accessible from the Internet. A quick way to find this out is to run this Linux command:

curl ; echo
