What happened: I am trying to set up a network of 5 nodes. I have created a testnet using tendermint create testnet and copied the config folder to the respective nodes. now when I run, tendermint node --consensus.create_empty_blocks=false on all the 5 nodes, 3 of them work fine but on two of them an error similar to this appears:

On the three nodes which are working correctly, there was already an instance of tendermint running before. The two nodes with error are fresh nodes.
I have also opened the ports 26656 and 26657 on al the machines.

What you expected to happen: I expected all the 5 nodes to work perfectly normally.

Have you tried the latest version: yes
