Hi @curiosity-hyf! I'm Dosu and I’m helping the dify team.

The 'Run App' button uses the app's base URL, which does not automatically include the port from your NGINX_PORT or EXPOSE_NGINX_PORT settings. To fix this, set the APP_WEB_URL environment variable in your .env file to include the correct host and port, for example: APP_WEB_URL=http://localhost:8090. Then restart your Docker containers to apply the change. This ensures the generated URLs (including the 'Run App' button) will open with the correct port as expected. For more details, see the relevant discussion and solution here and here.

To reply, just mention @dosu.
