Hello ,

Latest helm chart installed in AWS EKS and mender exposed via proper dns and certificate ( Nginx Ingress controller ) . The remote terminal functionaltiy doesnt work with below error .

{“error”:“websocket: the client is not using the websocket protocol: ‘upgrade’ token not found in ‘Connection’ header”,“request\_id”:“b244ce30-6daa-4a7a-b9af-0157c6244f8c”}

Is there any speical configuration to be done at ingress ?

Thansk,  
sudheer

Hi @sudheermygapula ,  
if you’re using the AWS Application Load Balancer, can you try the AWS Load Balancer Controller instead of the Nginx Ingress controller?

Hello @sudheermygapula ,  
with these settings in the helm chart, the remote terminal is working for us, in a setup with Ingress Nginx:

```auto
ingress:
  enabled: true
  ingressClassName: nginx
  path: /
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: "0"
    nginx.ingress.kubernetes.io/proxy-buffering: "off"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "600"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "600"
  hosts:
    - <your Mender host>
  tls:
    - secretName: <your TLS secret name>
      hosts:
        - <your Mender host>

```
