### Question
- What do you want to know?
When I deploy skywalking on kubernetes, it is running ok and can access data by accessing ip:12800. But when try to access ip:11800 I got the next error:
```

BTW, the same code that deploy on VM works ok.
Looking forward to your reply.

#### The agent access skywalking server through port 11800.
I start agent locally to test if the skywalking on k8s running ok, I saw the agent can connect with oap server, but the server got errors when agent sending data to it.

This error may be caused by your load balancer or proxy, which don't support http2/grpc very well.

I agree with your opinions.
SO I did the next operation:
Firstly, the agent connect with oap server by k8s service(LoadBalancer), does't work and then I use pod ip as oap server directly but got the same errors.
Anyway, thanks for your timely reply.

OK, if you package your own image, then it is hard to tell. You could find the official docker image on the docker hub.
