Hey there, @zhenPolaris! 👋 I'm here to help you with bug fixing, answering questions, and becoming a contributor. Let's squash those bugs together!

I found some similar threads related to 404 errors when accessing http://localhost/install in a Docker environment for Dify:

  1. After "docker compose up -d", Open URL http://localhost/install,i got an ERROR: http://localhost/console/api/setup 504 not found. - This discussion is unsolved and might provide some insights into similar issues [1].

  2. Unable to open http://localhost/install - Another unsolved discussion that might have relevant information [2].

  3. Help Problem starting the project - This is also an unsolved discussion that could be related [3].

For troubleshooting, consider the following steps:

  • Ensure all Docker containers are running smoothly by executing docker compose ps and checking logs for any errors with docker logs <container_name>.
  • Verify that the Nginx reverse proxy is correctly configured and running, as it handles routing for the application.
  • Check the environment variables in your .env file to ensure they are correctly set, especially those related to server configuration and URLs.
  • Review the Nginx configuration files to ensure they are correctly set up to route requests to the appropriate services.
  • Restart the Docker containers using: 
    docker compose down
docker compose up -d
  • Check for any CORS errors and update relevant URLs in docker-compose.yml if necessary [4].

These steps should help you identify and resolve the 404 error when accessing http://localhost/install.
