Did you manage to run your node?

No, looks like I can't connect, low peer count (0).

At first, I wanted a running node in the current sidechain. Later, if that works, maybe a Witness “upgrade” :-)

This is how it looks at the moment:

My .env:

# Database
MONGO_URL=mongodb://127.0.0.1
#MONGO_DB=echelon # empty
MONGO_DB=meeray # DB from mongorestore

# Kafka
KAFKA_BROKER=10.70.85.104:9092
KAFKA_ADVERTISED_LISTENER=PLAINTEXT://10.70.85.104:9092

# Notification System (must run Kafka)
USE_NOTIFICATION=false

# Steem
STEEM_ACCOUNT=echelon-m3

# Witness Keys => Maybe later
# WITNESS_PUBLIC_KEY=
# WITNESS_PRIVATE_KEY=

# P2P Networking
# comma-separated list, e.g. ws://23.94.30.150:6001,ws://peer2:6001
# Peers from https://api.meeray.com/peers
# PEERS="ws://::ffff:23.94.30.150:59428,ws://23.94.30.150:6001"
PEERS=""
P2P_PORT=6002

# HTTP API
API_PORT=3002

USE_STEEM_BRIDGE=false
STEEM_BRIDGE_ACCOUNT=echelon-node1
STEEM_BRIDGE_ACTIVE_KEY=XXX
STEEM_TOKEN_SYMBOL="STEEM"
SBD_TOKEN_SYMBOL="SBD"
# 
LOG_LEVEL=info
NODE_ENV=development

Any ideas? I'm standing in the forest...

You must publish your public key using the witness_register contract

I know how to do this with cli_wallet for Steem-Witness, but unfortunately I have no idea how to do it here.

It would be great if you could give me a tip on this. I'd be happy to reward you with some of my newly created ThankYouTokens (TYT) :-)
