I found similar threads discussing the issue of Dify being inaccessible in the browser despite the backend services running normally. Here are some relevant discussions and solutions:

1. Open Issue: Dify backend is running but inaccessible in browser suggests ensuring that your environment variables in the docker-compose.yaml file are correctly configured with your server's addresses. Specifically, set variables like CONSOLE_API_URL, SERVICE_API_URL, and APP_API_URL with your actual server domain. Additionally, make sure your application is not bound to localhost but to a publicly accessible domain or IP address. If Nginx is running on your system, stop it using sudo systemctl stop nginx, then restart the Dify containers with docker compose up -d. If you encounter a PluginDaemonInternalServerError: killed by timeout error, add PLUGIN_MAX_EXECUTION_TIMEOUT: 2400 to your docker-compose.yaml file ^[1].

2. Closed Issue: Prompt generator return HTTP 502 (Bad Gateway) was resolved by updating the Nginx configuration to point to the correct container IP addresses. You can check the IP addresses of your Docker containers using:

   docker ps -q | xargs -n 1 docker inspect --format '{{ .Name }}: {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}'

   Then, update the Nginx configuration in dify/docker/nginx/conf.d to use these IP addresses for the API and web services ^[2].

Additionally, it's important to note that version 1.0.0 of Dify has not been officially released and shows compatibility issues. It is recommended to use version v0.15.3 for production environments to avoid potential problems ^[3].
