Oracle Cloud Infra connection between instances not working

I have two instances in Oracle Cloud Infra. Both running Ubuntu 20.4. I have very strange problem. I cannot access Apache on instance 1 from 2 or even from public IP. Both instances are part of same Subnet. I have enable traffic from Security list, NSG. I can ping and SSH but just can't access apache page on port 80

ubuntu@docker1:~$ ping 10.100.246.237
PING 10.100.246.237 (10.100.246.237) 56(84) bytes of data.

ubuntu@docker1:~$

Instance 1 Docker1 = 10.100.246.50 Instance 2 Docker2 = 10.100.246.237

I tried using Oracle Linux but still same problem.

You also need to open the port 80 in your firewall on your Ubuntu instances. By default Ubuntu comes with UFW (Uncomplicated Firewall) so you can open the port with something like this : sudo ufw allow 80/tcp.

Oracle Linux uses firewalld.
