Unable to Connect to Docker Container Service via Local IP Address, Works with Loopback (127.0.0.1) #917
Description
I'm facing an issue where I can successfully perform a TCP connection using telnet to 127.0.0.1:5900 on the host machine, but I am unable to connect through the local IP address (e.g., 10.x.x.x:5900).
The Docker container is configured to map port 5555 inside the container to 5900 on the host machine, with the following mapping:
5555/tcp -> 0.0.0.0:5900
However, after checking the container's network configuration, I found that the service inside the container (specifically adbd for Android Debug Bridge) is listening only on IPv6 ([::]:5555), and IPv4 connections to the port are not successful.
This raises the question of why 127.0.0.1 (loopback address) works, but the local IP address does not. I suspect that the service inside the container is bound to IPv6 and needs to be reconfigured to listen on IPv4 to allow external connections.
