I’m sorry for any inconvenience caused. This limitation is due to nginx itself, not nginx-ui. We have configured a reverse proxy in nginx to forward requests to nginx-ui. Therefore, to access nginx-ui via port 80, nginx must be running.

However, this does not mean there is no way to access nginx-ui if nginx is not started. You can export the port that nginx-ui is listening on to the host, allowing you to access nginx-ui directly without going through nginx.
