I have fresh installation of Ubuntu server 22.04. I can't connect to my docker container. Here is some more information:

ufw status

curl 192.168.0.134 from device which I use to ssh access:

curl: (28) Failed to connect to 192.168.0.134 port 80 after 25916 ms: Operation timed out

same problem on browser (Chrome)

ping from host to server working:

ping 192.168.0.134

Any idea? In my opinion, docker and ufw is configured properly, I hope my router is not blocking anything (host is laptop with wifi, server is connected by cable, ssh working properly so devices have connection probably)

A timeout usually points toward a firewall issue. Check if there is another firewall involved.

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.
