failed to WebSocket dial: failed to send handshake request on private EKS
I have a private EKS cluster with cert-manager and DNS installed on the cluster. Attached are my test files. I exec inside the pod with a
coder template push -y

Queued [0ms]
==> ⧗ Running
==> ⧗ Running
Encountered an error running "coder templates push", see "coder templates push --help" for more information
error: API request error to "GET:http://coder.example.com/api/v2/templateversions/90463ed1-d72f-46bf-a4eb-e9f8f8d3d139/logs?follow". Status code 426
Trace=[begin streaming logs: ]

WebSocket protocol violation: Connection header "close" does not contain Upgrade
{"message":"Failed to accept websocket.","detail":"failed to accept WebSocket connection: WebSocket protocol violation: Connection header "close" does not contain Upgrade"}
```
This error also occurs when I'm not inside a pod. When I login to coder via CLI from outside the cluster, I get the same error.
kubectl exec command. Once I'm inside the pod I log into coder with the coder login command. From there I pull, modify, and push my template. When I run the coder template push command I get the following error:coder template push -y

Solution
Hey @Phorcys
I fixed the websocket error. Within my ingress annotations I had there following
nginx.ingress.kubernetes.io/websocket-service: “coder”
I just updated
nginx.org/websocket-service: “coder”
And everything started working. Now I just gotta figure out how to get coder web browser to use IPv4 instead of IPv6. I’m getting a 502 error and I try to open code-server in the browser. But I’m able to use VS Code Desktop just fine.
