I have followed the guide to the T.
even open related ports for TCP.
After doing these commands
$ sudo service heimdalld start
Start Heimdall rest-server
$ sudo service heimdalld-rest-server start
Start Heimdall bridge-server
sudo service heimdalld-bridge start
I am still getting curl: (7) Failed to connect to localhost port 26657: Connection refused
Can anyone point me in the right direction? thanks.
