firewall - Port seems to be open, but connection refused
Raw
Port is open, but connection refused
The port is running already it can be check through netstat -a.
But openning in browser refuses the connection.
This is due to firewall blocking the port, It needs to be allowed.
Check all port allowed by firewall:
sudo ufw status
Allow a port
sudo ufw allow 8890
