MM2 REST API returns 404 on all path

Kafka Connect Managed Connectors
1

I am running mirror maker 2 with dedicated mode on kubernetes, I have setup the endpoint to 0.0.0.0:8081, I can see that 8081 REST server are open, but it keep emitting 404 no matter what endpoint I use, such as

curl http://localhost:8081/connectors
curl http://localhost:8081/admin/loggers
curl http://localhost:8081/connector-plugins

I have tried with IP (what I put in the advertised listener), localhost, 0.0.0.0, 127.0.0.1

and it kept returning

{"error_code":404,"message":"HTTP 404 Not Found"}

curl http://127.0.0.1:8081/connectors -vvv
*   Trying 127.0.0.1:8081...
* Connected to 127.0.0.1 (127.0.0.1) port 8081 (#0)

< Date: Thu, 13 Feb 2025 12:32:56 GMT
< Content-Length: 49
< Server: Jetty(9.4.53.v20231009)

here is my config

dedicated.mode.enable.internal.rest = true
listeners = http://0.0.0.0:8081
rest.advertised.host.name = <INTERNAL_IP>
rest.advertised.listener = HTTP
rest.advertised.port = 8081

here are the logs stating that REST server has started
