Hello,
I've just installed Ubuntu 20.04 on my VPS and I have seen that not all ports are reachable. For example the 80 and 8080 ports are reachable, but 3000 port not. It seems that iptables does not have rules to block traffic and ufw firewall is disabled. On ovhcloud console admin there aren't rules to block traffic.
Can you help me please?
Thank you
