Failed to connect to localhost port 8080 after 0 ms: Connection refused - DOCKER VSCode

I'm trying to use docker with VScode using my mac (mac OS Monterey) and it always shows "Failed to connect to localhost port 8080 after 0 ms: Connection refused". Could anyone help? thank you much appreciated.

Exposed port unavailable after a while Hi! I'm very new to Apple, my first device is the Mac mini M1, I'm trying to expose some services (through Docker) but I currently have some problems. I investigated a little more and I found that my problem is not related to docker, once I try to expose a port directly with: ⚡ nc -lk 0.0.0.0 8888 and I try to connect from another devices (192.***.0.167 is the IP of the Mac Mini) here is what's happening: daniele@xxxxx /home/daniele ⚡ while true; do sleep 2; nc -zv 192.***.0.167 8888; done ^C daniele@xxxxx /home/daniele ⚡ nc -zv 192.***.0.167 22 Connection to 192.***.0.167 22 port [tcp/ssh] succeeded! daniele@xxxxx /home/daniele ⚡ while true; do sleep 2; nc -zv 192.***.0.167 8888; done Connection to 192.***.0.167 8888 port [tcp/*] succeeded! Connection to 192.***.0.167 8888 port [tcp/*] succeeded! Connection to 192.***.0.167 8888 port [tcp/*] succeeded! ^C [Personal Information Edited by Moderator] In the first attempt I don't get any answer, so I interrupt after a while; then a connection on the SSH port (remote login is enabled) "unlocks" the other ports, and finally if I try to connect it magically works! After a while the port becomes unavailable again and to access the service I must first connect to the SSH port. Could you explain me what's happening? Thank you
