I have deployed my Python Flet app in OCI (Oracle Cloud Infrastructure). When I connect to VM by SSH connection, I can run my program on local host 0.0.0.0:8000. Even when I forward port by tuneling to my local machine, I can see my app working at localhost:8000. However, entering the public address results in error, the webpage is not loading. I have added Ingress Rule as well (All type of connections, CIDR 0.0.0.0/0 and all ports. What could be the reason that I cannot access the app in public address? The IPV4 CIDR Block in public subnet is bound 10.0.0.0/24 and VCN IPV4 CIDR Block is 10.0.0.0/16. I guess that the problem is associated with incorrect addressing of ports, however, I am begginer to Oracle Cloud.
