Cannot visit taiga deployed on my own host

I was just following the 30min setup but it is unable to visit https://my_server_ip:9000
The netstat -tln shows that the port 9000 in my server is listening, but when I try to visit it through my browser, it just say it is unable to access and time out. docker ps shows that all of the 9 containers are started and the db is healthy.

Hi there!

Is your browser on the same host you installed Taiga, or a different host?

If it is on a different host, make sure you didn’t onfigure Taiga to listen only on localhost:9000

Best regards!
