How do I access my CometBFT endpoint externally?​

The default CometBFT port is at 26657.

To make it accessible externally, you'll need to port all the instructions from port 26656 on this page to port 26657. Specifically:

# Update your firewall
sudo ufw allow 26657/tcp

# Alternatively, if ufw is not available, update your iptables
sudo iptables -A INPUT -p tcp --dport 26657 -j ACCEPT

# Update your Cosmovisor config
sed -i 's|laddr = "tcp://127.0.0.1:26657"|laddr = "tcp://0.0.0.0:26657"|' $HOME/.poktroll/config/config.toml
sed -i 's|cors_allowed_origins = \[\]|cors_allowed_origins = ["*"]|' $HOME/.poktroll/config/config.toml

# Restart the service
sudo systemctl restart cosmovisor.service

# Test the connection
nc -vz {EXTERNAL_IP} 26657
