Fresh Coder helm installation fails Workspace creation

I created a coder instance using helm following step-by-step the docs using a custom TLS ingress that works fine. The installation has been successful, but when I try to create a workspace using the default kubernetes template, the Coder UI fails to connect with the pod with this error:

2025-03-12 11:37:47.707 [info]  connecting to coderd

2025-03-12 11:37:47.795 [warn]  run exited with error ...

    error= GET https://coder.mydomain.com/api/v2/workspaceagents/me/rpc?version=2.3: unexpected status code 403: unexpected non-JSON response ""

               Error: no response body

               Error: no response body

While in the coder controller I have these logs:

2025-03-12 11:32:19.395 [info]  provisionerd-coder-85cc58dcd5-b2mst-0.runner: apply successful  job_id=eea0a5f0-9e46-417f-a22c-d96f556dc68e  template_name=dev-machine  template_version=gifted_allen5  workspace_build_id=29a09c0b-75cb-458f-9c32-f9b1faecdd52  workspace_id=745d2861-d1ba-4cab-af60-3d9430baadb1  workspace_name=test  workspace_owner=admin  workspace_transition=start  resource_count=2  resources="[kubernetes_persistent_volume_claim.home kubernetes_deployment.main]"  state_len=35276

I attached the screen of what the UI shows, while on kubernetes the pod is in "running" state.

Solution:

@Phorcys I solved it! The problem was the ingress class I was using, I had to enable websockets in the annotations. For everyone who users Contour wondering how I solved it, this is the config: ```YAML ingress:...

I am also not able to connect to the istance using VSCode as I get this error:

Phorcys•2mo ago

hey, are you using a self-signed cert?

Arturo GhinassiOP•2mo ago

Hi, No the certification is issued by letsencrypt and is managed by an AWS load balancer. So the ingress https://coder.mydomain.com points to the Application Load Balancer that manages the certification and then redirects to the kubernetes masters ips.

Don't know if it helps, but I have also this other error from the UI:

Solution

@Phorcys I solved it! The problem was the ingress class I was using, I had to enable websockets in the annotations. For everyone who users Contour wondering how I solved it, this is the config:

ingress:
  enable: true
  className: contour
  host: coder.mydomain.com
  annotations:
    projectcontour.io/websocket-routes: "/"
  tls:
    enable: true
    secretName: mydomain.com

ingress:
  enable: true
  className: contour
  host: coder.mydomain.com
  annotations:
    projectcontour.io/websocket-routes: "/"
  tls:
    enable: true
    secretName: mydomain.com

I will close the issue on github with the answer.

Arturo GhinassiOP•2mo ago
