I'm using Eclair and have a conf file with content:
eclair.chain=testnet
eclair.node-alias=mynodename
eclair.node-color=ff0000
eclair.api.enabled=true
eclair.server.public-ips=["<ip one>","<ip two>"]
eclair.api.password="my-eclair-api-pass"
eclair.bitcoind.rpcuser=aqaqaqaqaq
eclair.bitcoind.rpcpassword=aqaqaqaqaq
eclair.bitcoind.zmq="tcp://127.0.0.1:29000"
eclair.gui.unit=sat
still I can't see my node in https://explorer.acinq.co/
I can open channels
[Edit 1] My pubkey is 03125205d1b5ae747064491d2b3b30b41fd7ec4e96e0ccede2f71c55891995f675
