Why Docker Apache Connection Refused?

There are various reasons why the “Docker Apache Connection Refused” issue may occur:

1. It’s possible that the exposed or mapped ports differ from the port that Apache listens on within the Docker container.

2. Apache may not start or listen on the expected port due to issues with the Docker container settings.

3. Apache may not be able to accept incoming connections if the host computer or network blocks connections to the specific port.

4. Issues pertaining to Docker networking, such as improper traffic routing by the bridge network of Docker or inability of the container to communicate with the host machine, can

Fixes

1. Check that Apache is set up correctly to listen on the desired port and that the config files don’t include any syntax problems.

2. Verify that Apache is up and functioning smoothly in the Docker container. To see a list of all containers that are currently operating, use the docker ps command.

3. Make sure the right ports are mapped if we’re using port mapping to expose the Apache service from the Docker container to the host computer. To provide port mappings, use the -p flag when running the docker container.

4. Verify that no security measures or firewall rules are preventing incoming connections to the specific port on the host computer.

5. Check that the container can communicate with the host computer and other network resources, and that Docker’s network settings is set up correctly.

6. Restarting the Docker service might occasionally fix problems with networking. Use the relevant command for the OS to obtain this (for example, systemctl restart docker on Linux).

7. Check for any error messages or warnings in the Apache and Docker container logs that could point to the source of the connection rejected error.
