I have a Django application accessible at port 8080. My current iptables is set

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy DROP)
target     prot opt source               destination         
DOCKER-USER  all  --  anywhere             anywhere            
DOCKER-ISOLATION-STAGE-1  all  --  anywhere             anywhere            
ACCEPT     all  --  anywhere             anywhere             ctstate RELATED,ESTABLISHED
DOCKER     all  --  anywhere             anywhere            
ACCEPT     all  --  anywhere             anywhere            
ACCEPT     all  --  anywhere             anywhere            

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         

Chain DOCKER (1 references)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             172.17.0.2           tcp dpt:redis
ACCEPT     tcp  --  anywhere             172.17.0.3           tcp dpt:9443
ACCEPT     tcp  --  anywhere             172.17.0.3           tcp dpt:8000
ACCEPT     tcp  --  anywhere             172.17.0.4           tcp dpt:8086
ACCEPT     tcp  --  anywhere             172.17.0.5           tcp dpt:3000

basically all my POLICIES are on ACCEPT but for some reason, if I access from any of my coputer on the local network with :8080 I got a connection refused. If I access from inside the localhost everything works fine.

What's blocking the connection on that port? Even if I change port (expect from port 80, I always get rejected)

I'm running ubuntu 22.04 LTS

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
