There could be several reasons why inter-container communication is failing even when a published port and host IP are being used:
Firewall or network settings: The firewall or network settings on the host machine may be blocking traffic from the container. Make sure that the necessary ports are open and traffic is allowed.
Container configuration: The container configuration may be incorrect, and the container may not be listening on the correct port.
IP address conflict: There may be an IP address conflict on the network. Make sure that the host IP address is unique and not being used by any other device on the network.
Docker networking issues: The Docker network may be misconfigured, or the container may not be correctly connected to the network. Verify that the container is connected to the correct network and that the network settings are configured properly.
DNS issues: DNS issues may prevent the containers from communicating with each other. Ensure that the container names and IP addresses are properly resolved in the DNS.
Container runtime issues: There may be issues with the container runtime that are preventing it from communicating with other containers. Check the logs for any errors related to the container runtime.
