Hello,

What I would usually do in such cases is:

  • First check if the process is actually listening on that port:
netstat -plant | grep 8000
  • If the port is actually being used, then make sure that it is open for incoming traffic via your firewall. If you are using Ubuntu and UFW, you could do that with:
ufw allow 8000

Hope that this helps!
Regards,
Bobby
