Drone and Runner not communicating properly behind reverse proxy!

Drone Support
1

Hi!

I have tried to setup Drone and a runner behind a reverse proxy (I use Nginx Proxy Manager to manage the proxies).

I can access the Drone and runner dashboard from:
https://drone.domain.com
https://runner.domain.com

I have a small test build that looks like this:

name: drone-test
kind: pipeline
type: docker
platform:
  os: linux
  arch: arm
steps:
- name: test
  image: alpine
  commands:
  - echo "It worked!"

The Ngnix proxy config for the Drone looks like this:
https://build.domain.com → http://drone:80

And the runner:
https://runner.domain.com → http://runner:3000

When I do a push to my repo I can see that the build gets started in the dashboard but its just stuck on 0% and spins forever.
In the logs I can see this:

Does anyone have any idea what might be the problem?
I have been stuck with this for a couple of days and any help would be greatly appreciated, thank you all!

Hello @TheGreyRaven

I can see from the runner output that it is polling for the arm64 architecture, however, the platform section in your yaml specifies the arm architecture.

platform:
  os: linux
  arch: arm

Since the architectures do not match, the pipeline does not get picked up by the runner and sits in a pending state. Could you please try making this change so that the Arch that the YAML is looking for and the runner is on is the same.

Thanks & Regards,

Thank you it worked now!
I’m ashamed that I did not notice that, thank you again! :smile:
