    Compared to another normal machine, the port of 80 is not monitored, perhaps the problem is here.

@ZiAn-Su Hello there! I'm here to help you with bug fixes, answer questions, and guide you on becoming a contributor. Let's tackle this issue together!

There are similar discussions and issues related to your problem:

  1. Unable to open http://localhost/install - This discussion is unsolved and might provide insights into similar issues.
  2. Help Problem starting the project - Another unsolved discussion that might be relevant.
  3. Local Docker Setup Failure - This unsolved discussion could also be related.

A similar closed issue, docker does not rewrite specific URLs into the system, suggests that the problem might be due to the Nginx reverse proxy configuration. Here are some steps to resolve this issue:

  • Ensure that the NGINX_SERVER_NAME is set to the correct domain name.
  • Verify that NGINX_PORT and EXPOSE_NGINX_PORT are correctly set.
  • If HTTPS is enabled, ensure SSL certificates are correctly configured and NGINX_SSL_PORT and EXPOSE_NGINX_SSL_PORT are set appropriately.
  • Ensure environment variables for the API, worker, and web services are correctly set in the docker-compose.yaml file.
  • Ensure CORS settings are correctly configured to avoid cross-origin issues.
  • Use a .env file to manage these environment variables persistently across deployments [1].

Additionally, the issue could be related to port 80 not being monitored. Ensure that the docker-nginx-1 container is mapping port 80 to the host. If port 80 is being used by another service on your Windows 11 machine, this could prevent access to http://localhost/install. Verify if the container is running and check for any port conflicts [2].

cp .env.example .env

Yes everything seems okay to me, however you missed editing those variables when you deploy to another machine.

My problem has been solved.
My WSL has two subsystems, Linux and Docker Desktop. The default subsystem is Linux. When the Docker service is enabled, messages are forwarded to the Linux system. In the Linux system, curl http://localhost:80 can be accessed, but Windows can't access.
After setting Docker Desktop as the default system, Windows can access curl http://localhost:80 .
