[beatenevo]

It only supports compatibility with Nacos 2.x and is incompatible with Nacos 3.x owing to authentication.

Thanks for the feedback. The code already supports Nacos 3.x authentication through registry.WithUsername() and registry.WithPassword().

To use Nacos 3.x, simply configure the credentials in your .env file:

NACOS_URL=localhost:8080  # Nacos 3.x uses port 8080
NACOS_USERNAME=nacos
NACOS_PASSWORD=nacos

Please refer to the https://nacos.io/docs/latest/auth/ for setting up Nacos 3.x server with authentication.
