and try again in a few minutes.This could happen if the firewall is not open for the ports used by the app for external connections for example you can open port 8080 using these commands:
centOS
Ubuntu
sudo firewall-cmd --zone=public --add-port=4000/tcp --permanent
sudo firewall-cmd --zone=public --add-port=4001/tcp --permanent
sudo firewall-cmd --zone=public --add-port=4002/tcp --permanent
sudo firewall-cmd --zone=public --add-port=4003/tcp --permanent
sudo firewall-cmd --reload
sudo ufw allow 4000
sudo ufw allow 4001
sudo ufw allow 4002
sudo ufw allow 4003
ufw reload
