I’m using this docker-compose file: https://github.com/zeltsi/lnsim
It works fine with regest (without modification)
Then I changed regtest for testnet (all 4 occurences)
Now I have this error:
lightning-cli: Connecting to ‘lightning-rpc’: Connection refused
> lightning-cli --version v0.12.1
Both bitcoin nodes are synced.
So what is the difference between regtest and testnet ?
